Governor Springs, Bushings, Links, Linkages, Throttle Cable Clamps, Throttle Cable Assemblies and Governor Gear Assemblies and Related Parts [Top of Page]
   Throttle Stabilizer/Anti-Surge Springs. Install either of these lightweight springs connect between the governor lever and throttle lever to remove free play (looseness) in the linkage end connections to reduce erratic engine behavior at top governed speed due to throttle flutter for a smoother running engine and reduce wear to throttle shaft. Can be used on virtually any Briggs & Stratton, Kohler K-series, Magnum or Command single- or twin-cylinder cast iron or aluminum block engine. May need to drill a small hole with chamfered edges in either lever close to linkage connection to install spring. A must for a generator, welder or a 4,000 RPM± governed competition pulling engine. With a governed pulling engine, throttle flutter causes the engine RPM to momentarily spike, which will cause the rear tires to temporary lose traction (jerk), resulting in a possible shorter distance pull. An ingenious and innovative concept by Brian Miller, because nobody else advertise this type of product for a governed pulling engine.

   Kohler Governor Cross Shaft Bushings with Rubber Lip Oil Seal or Neoprene Rubber O-Ring Installed. Seal or O-ring fits snug in bushing and on shaft, and has no effect with operation of governor function whatsoever. WHY THIS IS IMPORTANT: On single cylinder Kohler engines, vacuum within the crankcase created by the upward stroke of the piston draws in outside air, along with a small amount of dust, dirt/debris, through the governor bushing and shaft, then pressure within the crankcase created by the downward stroke of the piston blows out a fine mist of crankcase oil through the bushing and shaft. Overtime, the dust, dirt/debris of this repeated reciprocating action cause the bushing (and sometimes the shaft, too) to wear, which creates a thin film oily mess on the outside of the engine block. IMPORTANT: When removing the old bushing, use caution not to drop the governor cross shaft down inside the crankcase! (Complete disassembly of the engine will be required if this happens.) And before installing any new oil seal or rubber O-ring, always apply clean motor oil, gear oil or lubricating grease inside seal or O-ring and on shaft to keep seal or O-ring lubricated and cool until crankcase oil can reach it. With no prior lubrication, the dry rubber will wear away from friction, possibly causing an oil leak. An ingenious and innovative concept by Brian Miller, because nobody else advertise this type of product or service.  Governor Cross Shaft Bushing with 7/32" hole. Fits Kohler engine models K90/K91, K141, K160/K161 and K181 w/specification # 30100-30848 and various early M8 engines with V-shaped/coiled governor spring behind bushing.

 Thrust Washers for Governor Gear Assemblies. A thrust washer is required to prevent the governor gear from wearing against the engine block when the governor gear is under full pressure from the engine running at higher RPMs. Many people are not aware of this small, thin washer because it may appear to be part of the engine block, and it usually falls out and gets lost while cleaning inside the block. IMPORTANT: Due to high RPM and pressure of the governor gear upon engine start-up, before installing, lubricate the stub shaft and thrust washer with motor oil, automotive chassis lube or wheel bearing grease to prevent the governor gear from wearing until the crankcase oil reaches these areas.
Governor Gear Stub Shafts. Fits Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16, K361 and all KT-series and Magnum opposed twin cylinder engines. Dimensions: 3/8" diameter x 7/8" length.

Operates totally independent of the ignition system. Can be used for lawn & garden equipment or competition pulling engines. Designed to be permanently mounted to monitor engine RPM at all times. Tachometer can be in-dash or panel-mounted. This precision digital tachometer operates with external power and on the same principle as my flywheel- or crank-trigger ignition systems with a proximity sensor to detect the target, which can be a small ferrous steel screw or pin, or magnet in a rotating disc on the crankshaft or on/in flywheel. A sturdy steel or aluminum bracket will need to be fabricated by customer to mount the sensor in close proximity of the detector/trigger target. Set air gap/clearance at .010"-.188". Tachometer works with 8-24 volts DC, proximity sensor works with 6-36 volts DC. Dimensions for mounting hole for tachometer: 3" wide x 1-17/32" wide. Tachometer measures 1" in depth. Dimensions of proximity sensor: 15/32" diameter x 1-3/8" thread length. Wiring Instructions: #1 wire on tachometer connects to brown wire on proximity sensor and ignition switch (12 volt power), #2 wire on tachometer connects to blue wire on proximity sensor and engine/chassis ground (battery negative (–) post), and #5 wire on tachometer connects to black wire on (either) proximity sensor. Wires #3 and #4 connects to nothing. Wiring is the same for the hall effect and inductive proximity sensors. Some proximity sensors have an LED (Light Emitting Diode) on the rear of unit. If the proximity sensor is wired incorrectly, the LED will illuminate within the target. Click or tap here for YouTube videos to see how well this tachometer works. Cannot be wired in conjunction with the Dynatek Dyna S or PerTronix Ignitor ignition modules. This tachometer must be wired separately or wiring can be integrated with my crank-trigger ignition system that use a proximity sensor.

| NOTE: High-quality ring sets, pistons and piston/rings assemblies are also available for other makes and models of small gas engines. And the piston assemblies that's offered here will work with a stock connecting rod and crankshaft without the need for rebalancing. And always match a billet connecting rod of a certain length to an aftermarket piston (Arias, JE, etc.) that has the correct compression height. These two parts must be matched for the piston to come flush with the top of the engine block, or have a few thousands of an inch pop-out. If using a Kohler connecting rod, the compression height may not be correct with an aftermarket piston (Arias, JE, etc.) that has the wrong wrist pin offset. The same is true with a Kohler piston and a billet connecting rod of a the wrong length. You can find piston ring compressors on eBay. |

 Upon installation of a connecting rod in a Kohler engine, the oil hole in the cap face toward the camshaft! There's "match marks" on both the rod and rod cap. They MUST be aligned or "matched up" so the big end of the rod forms a perfect circle around the crank journal when installed. Otherwise, if the cap is installed backwards, the "perfect circle" will be oblong or "egg-shaped," which will bind on the crank journal. And DO NOT over-tighten the rod bolts or nuts! If the threads strip out in a rod, then perhaps a longer grade 8 fine thread bolt can be installed in reverse to serve as a stud (the rod will need to be machined for head bolt clearance) and use a grade 8 nut. If this cannot be done, then the rod is scrap metal. |
 Connecting rods. Fits Kohler engine models K90/K91. NOTE: Crank journal must be reground .010" undersize to match this rod. The alternative to using an undersize rod is if a STD size or .010" undersize rod is in good condition, if the matching-size crank journal isn't deeply scored and/or badly burnt, it can be reground until it's perfectly round again and then if the original rod also isn't deeply scored and/or badly burnt, it can be resized to fit to odd-size undersize journal with the factory recommended .0025" oil clearance. NOTE - The maximum a connecting rod can be resized to is .005" undersize. If it's resized more than .005", being the big hole in the rod will be made excessively oblong or egg-shaped, which will allow it to make less bearing surface contact around the crank journal after being resized, due to the centrifugal force at 3,600 RPM, the big end of the rod could become elongated (metal stretch) and might eventually knock and possibly break. IMPORTANT: To prevent scoring of the rod when the engine is started for the first time, apply clean motor oil, gear oil or lubricating grease or on crank journal before installing rod. This will better protect the parts until crankcase oil reaches them. IMPORTANT: Click or tap here for proper break-in (wear-in) oils and procedure for rebuilt engines.

 STD size, .010", .020" or .030" (hard to find now) undersize Replaceable Tri-Metal (Lead Alloy/Copper/Steel) Bearing Inserts in Connecting Rods for Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16, K361 M20 and MV20. Rods for the before mentioned engines can be bored and notched to accept bearing inserts. Even severely burnt, scored, or rods with a mismatched cap can be bored for installation of bearing inserts. Only USA-made Clevite 77, Federal Mogul or Sealed Power bearing inserts will be installed. No low quality Chinese-made bearing inserts ever installed. All A-1 Miller's Professional Machined connecting rods include ground-out notches to prevent bearing rotation in rod and drilled oil hole for proper lubrication. Please indicate diameter of crank journal for size of bearing inserts. (STD size, .010", .020", .030" or resizable .060" undersizes.) Also, rods can be center-bored for top of piston to come flush with deck, or bored .020"± offset for a .020"± piston pop-out at no extra charge.
NOTE: If a crank journal is worn beyond specs or badly scored/burnt,it will need to be reground to the next undersize to match the appropriate size bearing inserts. And if you wish to have A-1 Miller's to bore a rod for you, please let me know if you want the bearing insert centered in the bore of the rod (5.300" rod length; piston flush with top of block), offset .020" (5.320" rod length; safe to use with a milled OEM Kohler stock head and stock head gasket) or offset .060" (5.360" rod length; use with a non-milled OEM Kohler head and stock head gasket) to pop the piston out of the cylinder (see below Ê) to raise the compression and help improve airflow within the combustion chamber for more power and torque. The bearing inserts I install in Kohler 10-16hp flatheads and 18hp OHV K361 connecting rods can be used for general lawn and garden use, stock or high RPM competition pulling engines. The rod will need to be bored exactly 1.625" for correct bearing to journal oil clearance. NOTE: Being virtually all Kohler K241/M10 pistons come within .020"± from the top of the block, which lowers the compression ratio. (The factory made them this way for reasons unknown.) I prefer to bore the K241 10hp rods .020" offset so the piston will come flush with the top of the block. This will allow the engine to produce a little more power. It won't effect the longevity of the engine or cause any problems whatsoever. But sometimes with the .020" offset, the piston will pop out of the cylinder a few thousandths of an inch, which will still hurt nothing. And the bore can be offset .040" for a .020"± piston pop-out. FYI - Before I machine a rod for installation of bearing inserts, I use a metal "plug" alignment tool that I fabricated to precisely align the big hole of the connecting rod with the centerline of the spindle in my milling machine. Then while the plug is in the rod, I firmly clamp the rod to the milling machine table and after leaving the big hole centered or moving the table so many thousandths of an inch offset for piston pop-out, I lock the table so it won't move in any direction while boring the rod. But for reasons unknown, sometimes the cutting tool will bore the hole in the rod slightly off-center toward one of the bolts or studs. When this happens, I simply grind a small notch on the outside of each bearing shell so they'll clear the rod bolt. I've talked to other machinists who bore Kohler rods also about this and they tell A-1 Miller's sometimes the same thing happens to their rods. But as long as the outside of the bearing shells are notched for clearance of the bolt or stud, the off-center of the bearing inserts poses no problems whatsoever. And bearing inserts for the 10-16hp Kohler engines can be installed in Kohler engine models K482, K532 and K582 STD size connecting rods, but the crank journals would need to be reground exactly to 1.500" to match the inside diameter of the bearing inserts when installed in the rods. And for your information, STD size crank journals for the K482, K532 and K582 engines measures 1.6245". |
 High Quality 8 Ball Main Crankshaft Radial Bearings. Fits Kohler K-series and Magnum cast iron block engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361. Heat treated chrome steel (AISI 52100) for higher resistance and durability. Supports up to 17,000 RPM. Bigger balls rotate freer and run cooler, which create less rolling resistance and friction than 12 ball bearings with smaller balls. (It's just like small tires on a 4x4 or 4WD truck/vehicle versus big tires - the bigger tires will roll with less resistance, especially over rough terrain.) Works excellent for general lawn and garden engines or for high performance competition pulling engines that run at high RPM or at wide open throttle. Dimensions: 1.57" (40mm) I.D. x 3.54" O.D. (90mm) x .90" (23mm) width. See note below Ê . NOTE: If your bearing(s) have more than .005" of play due to wear, or it feels rough or "rubbles" when rotated by hand with motor oil applied, then it should be replaced. FYI - All US and import manufacturers of ball bearings have always been made them to the metric dimensions. Where applicable, the manufacturers try to make them close as possible to the inch dimensions.

Fits Kohler engine models KT90/KT91. OEM Kohler part # 220009-S. $45.05 each, plus shipping & handling. NOTE: Before lapping in valves, it's best to have the valve seats recut or reground so they'll be in correct alignment with the centerline of the valve guides. Otherwise, the valves may not make a full 360º contact with the seats, resulting in leakage and the engine will lose compression, be hard to start, lose power and possibly make a popping sound through the carburetor or out the exhaust at idle speed. And be sure to set the clearances correctly, too. And if the end of the valve stem is accidentally ground too short, it can be made long again by building up welding with a MIG or TIG welder, then ground to the correct valve clearance.

| Valve Guides - FYI - Valve guides are made of either cast iron or bronze, and not steel. Cast iron and bronze are very hard and porous metals. They absorb oil and lubricate the valve stems for longer wear. [Return To Previous Paragraph, Section or Website]
NOTE: The alternative to installing new replacement OEM-type valve guides is to have the old [worn] guides reamed for installation of thin-wall bronze sleeves/liners (bushings), which can be installed by a reputable automotive machine shop. Bronze valve guide sleeves/liners are a low-cost alternative to replacing the entire guide in most engines. Bronze also last longer than cast iron guides because bronze is harder material and it retains more oil for better lubrication of the valve stem.  High Quality, High Speed Steel 5/16" (.3125") Chucking Reamer. Use to clean carbon deposits from used valve guides or enlarge new guides for a 5/16" valve stem in flathead 7hp+ B&S, Kohler, 8hp+ Tecumseh, etc. engines. $15.00 each, plus shipping & handling. | |
 A-1 Miller's Valve Guide Removal and Installation Tool for use with all Kohler K-series and Magnum engines. IMPORTANT: The engine block could crack if guides are removed or installed with a hydraulic press! Therefore, it's best to use a big, heavy hammer to drive out the old guide into the valve spring compartment and use the same hammer to install the new guide from inside the valve pocket. When installing the new guide, be sure to hammer straight down in alignment with the guide and not at an angle. Hitting the guide at an angle could cause it to break. Install new guides until flush with the valve pocket. This tool can be used with either OEM Kohler and aftermarket offset valve guides. Machined at a 90º angle where the pilot meets the shank. Dimensions: .300" pilot x 1/2" diameter shank x 5" overall length. An ingenious and innovative concept by Brian Miller. Please accept no advertised copycat products of this kind. (But I do appreciate them acknowledging my ingenuity and intelligence.)

High Quality, High Speed Steel Chucking Reamers. Precision ground to provide correct stem to guide clearance. Will not allow valve stem to be too loose or too tight in guide. When reaming guide, use an electric hand drill with plenty of oil in guide. Before installing valve, apply motor oil on stem for lubrication to reduce wear to guide and prevent valve from sticking. [Return to Previous Section, Paragraph or Website]

 Valve Stem Seals. Required to prevent crankcase oil from draining down into (OHV) or being suctioned into (flatheads) the combustion chamber through the guide. Silicone rubber w/metal clamp. NOTE: Apply clean motor oil, gear oil or lubricating grease on valve stem before inserting valve through seal to provide lubrication of the stem, guide and seal. Dimensions: 5/16" I.D. (stem) x .500" I.D. (guide) x .600" O.D. NOTE: Some early production KT17 models do not use valve stem seals.

High Quality Valve Lapping Tools with Wooden Contoured Grip. After the valve faces and seats have been professionally recut or reground in a valve refacer machine and valve seats recut or reground with a valve seat grinder/grinding stone, and valve clearances have been set to specifications, apply valve grinding/lapping compound (which can be purchased online and at virtually any auto parts store) on the valve faces and according to valve size, use these tools to rotate the valve in its seat back and forth by hand (lap-in the valves) to create a rough surface on the valve face and seat so the valves will eventually wear into seats, forming a perfect seal allowing the valves to last longer and so the engine will have more compression to produce more power. IMPORTANT - Always thoroughly clean the valve grinding/lapping compound from the valves and seats, and inspect the valve face and seat for 360º contact before installation of the valves!

 New-Style, One-Piece, Plain, Ordinary OEM Camshafts with Automatic Compression Release (ACR). Fits Kohler K-series or Magnum engine models K241/M10, K301/M12, K321/M14 or K341/M16. IMPORTANT: To prevent seizing of camshaft on pin when engine is ran for the first time, apply plenty of motor oil on cam pin and inside cam before installing cam in engine. This will better protect the parts until crankcase oil reaches them. When reusing lifters, roughen lifter faces with 600 grit sandpaper to produce a new wear pattern and so the lifters will rotate slightly with every lift to prevent wear to the cam lobes. And the lobes on the used cams have not been reground for performance.

Professionally Reground 4,000± RPM Performance Torque Cam for Kohler EnginesFYI - In order to gain the full benefit of a performance camshaft, just installing this type of cam will not greatly increase the power output of a Kohler engine. Along with the performance cam, the carburetor will need to be bored-out and reworked, the cylinder head will need to be milled .050" to raise the compression ratio, the valves/seats will need to be reworked, and installing an open/unrestricted exhaust header pipe will help, too. All of these things must work together so more air will enter the combustion chamber (and exit the chamber), which will build up more compression to allow the engine to produce more horsepower and torque.
FYI: When the cam lobes are reground, metal is removed from the base circle which reduce the diameter of the base circle in order retain maximum lift at the point on the lobe. The ramps on the lobes are also "rounded" to give the cam more duration. The cam grinding machine's grinding stones are about 1" wide, and after the cam grinding process, I have to manually grind metal away from the sides of the base circles so the edge of the lifters won't "ride up" on the ungrounded areas and hold the valves slightly open when they're supposed to be fully closed. I have to do this to every reground cam I have in stock. Some cam grinders apply a phosphate conversion coating (which resembles flat or matte black paint) to the entire camshaft, especially the lobes. This coating is to prevent galling (wear) during the break-in period and it also covers the secondary grinding areas on each side of the base circles of the lobes so they can't be readily easily seen or noticed. Motor oil with high zinc phosphate content will also protect the cam lobes and other internal moving engine parts from wear during break-in. Otherwise, if everything else is set up correctly with your engine, this cam should work fine. There's no need to be concerned when you receive the cam and see the metal ground away. Also, some of the cams I have, the points lobe is slightly worn. (It's hard to find a good used, 100% unworn cam nowadays.) I include a stainless steel points pushrod with a flared-end to make contact with the unworn areas of the lobe. The pushrod will need to be installed from inside the block before the cam is installed. IMPORTANT: To prevent seizing of camshaft on pin when engine is ran for the first time, apply plenty of motor oil on cam pin and inside cam before installing cam in engine. This will better protect the parts until crankcase oil reaches them. Differences in Camshafts for Kohler Pulling Engines -

| FYI: The OEM valve springs in various models of Kohler cast iron block engines are not the same. They are not like the OEM springs that's used in a stock small block Chevy V8's, which are the same. For some reason, Kohler installed a specific valve spring in a certain model engine to match the cam profile (lobe lift and duration) so the engine will perform best. And used valve springs rarely lose adequate pressure. They can be reused as long as they're not rusted or have been overheated. The rust-pitted areas is a weak spot and when in operation and under pressure, the spring could break.

| A-1 Miller's Professional Valve Repair Service for Kohler Engine Model K361 Cylinder Head. [Top of Page] This service is for an engine that does not blow blue smoke out the exhaust and burn oil. Performing a professional valve job restores full compression, which allows the engine to start quicker, idle smoothly without stalling, and (if the ignition timing and carburetor adjustments are set correctly, too), it will produce full power at top governed speed. Click or tap here for cylinder head bolt torque specs. And if you've ever wondered how the K361 rocker arms receive plenty of oil to keep them lubricated, when the engine is running at full governed speed, internal air pressure from the downward stroke of the piston forces crankcase oil through the pushrod tubes onto the rocker arms.
FYI - I have found that the Kohler K361 18hp OHV cylinder head use the longer 1-3/4" valve spring (uncompressed length; discontinued Kohler part # 235010-S) with rotators for both valves, the same spring that certain early K241, K301 and K321 engines use with the stamped retainer. And of course, certain later K241, K301, K321, and all K341 engines have the shorter 1-9/16" spring (uncompressed length; discontinued Kohler part # 235168-S) with the rotator. Anyway, the official Kohler parts manual says that the K361 use the shorter 1-9/16" springs (with rotators) for both valves, but apparently, it's wrong! It obviously requires the longer 1-3/4" springs (with rotators). And of all the K361 engines that I've rebuilt through the years, with the 1-3/4" springs and rotators installed, there is no coil bind. Coil bind is when the coils of the spring make contact with each other at maximum valve lift. I've had a customer send his K361 head to me for repairs, and when I spoke to him on the phone about his engine, he mentioned that the engine had always made a chattering/rattling sound at full governed speed and lacked sufficient power. So I checked the valve springs, and sure enough, it had the shorter 1-9/16" springs (with rotators). My customer was lucky it didn't drop a valve. That would've been a nightmare! So I installed a set of the longer 1-3/4" springs (with rotators). The valves felt stiffer when I pushed down on them with my hand, too. - Brian Miller |
 A-1 Miller's Professional Repair Service - Resurface air-cooled small engine flathead or OHV cylinder head on large disc sander or wide, flat belt sander to remove warpage and restore flatness for better sealing of head gasket and prevent possibility of burning-out of [high dollar] head due to severe warpage. (Sanders are not just for woodworking.) Includes deburring of sharp edge around combustion chamber to prevent detonation or pre-ignition. Click or tap here for cylinder head bolt torque specs. $10.00 labor, plus return shipping & handling. NOTE - If it's repairable, please do not discard your cylinder head or other OEM Kohler parts. Most discontinued Kohler parts in good, usable condition are hard to find nowadays, and nothing works better than the original part(s) the engine was designed for. |
 A-1 Miller's Professional Repair Service - Mill approximately .050" from Kohler K241/M10, K301/M12, K321/M14 or K341/M16 cylinder head to raise compression ratio approximately .75:1 to increase horsepower and torque. Includes remove prominent/raised gasket mating surface from head and deburr sharp edge around combustion chamber to prevent detonation or pre-ignition. Click or tap here for cylinder head bolt torque specs. $25.00 labor each, plus return shipping & handling. NOTE: To lessen the chance of a blown or leaking head gasket, clean out the head bolt hole threads with a tap, and seal the head gasket with Copper RTV Silicone Sealant (VersaChem - Mega Copper Silicone, Permatex® Ultra Copper® Maximum Temperature RTV Silicone Gasket Maker or Copper SPRAY-A-GASKET Hi Temp Adhesive Sealant) on each side of the head gasket or cylinder head and engine block to prevent a blown or leaking head gasket. Because engine heat has very little effect on silicone rubber. It's made of fine-ground up heat-transferring compressible copper mixed with silicone. Walmart and most auto parts stores sell copper RTV silicone sealant. It doesn't matter which brand to use, they work the same. |
| A-1 Miller's Professional Repair Service - Professionally weld up burned-out gasket surface in small engine cylinder head, resurface on a wide sanding belt to remove warpage and restore flatness, and redrill bolt hole, if needed. The welding process involves grinding away the impurities in the aluminum, and the aluminum welding becomes integrated with or part of the aluminum in the head, resulting in superior bonding with no separation whatsoever. NOTE - As long as there's no cracks in the head, it can be successfully welded up, resurfaced, and the bolt hole redrilled. IMPORTANT - The two causes of a burn-out are: 1) Throttle shaft in the carburetor is severely worn, allowing extra air in the combustion chamber, which will lean out the air/fuel mixture at high RPMs; 2) The adjustable high speed main air/fuel mixture screw is set too lean; 3) The engine is ran above 3,200 RPM with a [Walbro] carburetor having a fixed/non-adjustable high speed main jet. To prevent the burn-out from happening again, either of these things should be fixed correctly before the cylinder head (engine) is put back into service. $75.00 for welding and machining, plus return shipping & handling. If it's repairable, please do not discard your cylinder head or other OEM Kohler parts. Most discontinued Kohler parts in good, usable condition are hard to find nowadays, and nothing works better than the original part(s) the engine was designed for.

 High Quality Cylinder Head Bolts and Flat Washers. Fits Kohler engine models K141, K160/K161, K181 and M8. OEM Kohler head bolts can be reused multiple times. They will not stretch overtime and are not "torque to yield." But replace bolts with eroded, rusted heads to prevent socket from slipping so bolt will torque down correctly. 5/16" diameter x 1-1/2" thread length grade 8 bolts and hardened washers. NOTES: Clean the threads in the block with a 5/16-18 UNC plug hand tap so the bolts will torque correctly. Then apply motor oil on the threads and torque each bolt to 240 in. lbs. or 20 ft. lbs. Liquid threadlocker is not necessary. Click or tap here for cylinder head bolt torque specs.
High Quality Aftermarket Single Cylinder Head Stud Kits. These studs can be reused multiple times. They will not stretch overtime and are not "torque to yield." Fits Kohler engine models K241/M10, K301/M12, K321/M14, K341/M16 and K361 with an OEM or Billet Head. Each kit includes 3/8" diameter x 2" or 2-3/4" length high quality heat-treated studs, grade 8 nuts and hardened flat washers. I can also make the head studs any length you want. The ones that's listed here are the most common lengths. When installed correctly and torqued to specs, head studs provide even torque pressure for better head gasket sealing. Plus, with a thinner cylinder wall with a huge, oversized piston, they help maintain cylinder wall stability and straightness for better ring seal to lessen the loss of compression. Thoroughly tested for several years of continuous use under pulling conditions, for Kohler engine models, hardened and heat-treated coarse thread studs, along with grade 8 nuts and washers, works just fine, with no problems. The nuts maintain their torque as long as they're tightened to the correct torque specs. And make sure at least 3/4" of threads are in the block so the cylinder wall will not distort and threads in block will not strip out when the nuts are torqued to specs. Click or tap here for cylinder head bolt torque specs. (Cast iron is weaker than hardened steel.) Also, the flat washers goes under the nuts to distribute even pressure across head. IMPORTANT: As with any threaded stud, apply medium strength liquid threadlocker (Blue Loctite, Permatex or equivalent) on threads that goes in the block to prevent stud from loosening. FYI - When storing an opened container of liquid threadlocker or Super Glue, store it upright and not laying flat. The [capped] tip will not dry out and clog when stored upright. Thread stud 3/4" into the block. Use a hardened flat washer under nut to distribute load across head and apply motor oil on exposed threads so nut will torque correctly. Torque each nut to 360 in. lbs. or 30 ft. lbs. in correct sequence. Also, stud length is determined by type of cylinder head. The OEM head with short bolt holes require 2" length studs, the head with tall bolt holes require 2-3/4" length studs. Please indicate length of studs when placing order.

Magnetic Oil Drain Plugs with Tapered Threads and Square Head listed below. A-1 Miller's oil drain plugs have a super strong rare earth/neodymium magnet. Five times stronger than competitor's ceramic (ferrite) magnet and resists demagnetization. Plugs listed below can be used on various other makes and models of transmissions, transaxles, gearboxes and small engines. Tapered threads requires no sealing gasket or sealant, and threads will not strip out when tightened. To avoid cracking oil pan, do not over-tighten! When in doubt, use plumber's thread sealing tape to insure proper sealing of threads to prevent a possible oil leak. Universal application. Magnet attracts and removes ferrous metallic wear fragments from the motor oil or transmission/gearbox to reduce engine or gear/bearing wear. Sometimes some of the ferrous wear fragments settle to the bottom of the oil pan and do not drain out with the oil when performing an oil change, even when the oil is hot. The engine will last much longer due to cleaner oil. Magnetic drain plugs are suitable for engines with splash oil lubrication (no oil pump/filter). Remember - Metal flake looks good in paint, not in oil.   1/4" NPT Magnetic Oil Drain Plug. (0.540" O.D. tapered threads.) Fits various Briggs & Stratton, Kohler and Tecumseh engines.

 Super Strong Rare Earth/Neodymium Magnets for Engines, Transmissions, Transaxles and Gearboxes. Attracts and removes ferrous metallic wear fragments from the lubricating oil inside an engine that does not have an oil pump with an oil filter, or inside a transmission, transaxle or gearbox to lessen wear and noise to gears and bearings. Sometimes some of the wear fragments settle to the bottom of the oil pan, engine block or gearbox and do not drain out with the oil when performing an oil change, even when the oil is hot. Engine or gears/bearings will last longer due to cleaner oil. Install magnet in bottom of oil pan away from the oil dipper and any moving parts, or in bottom of a transmission, transaxle or gearbox away from rotating gears and any moving parts. Use Krazy Glue, Super Glue, Gorilla Glue, or any industrial strength adhesive to secure magnet in place. These rare earth/neodymium magnets are EXTREMELY strong! Use caution when handling! Can be difficult to remove from a steel or cast iron surface, are very brittle and can break easily if mishandled. Remember - Metal flake looks good in paint, not in oil.

 Oil Filter Adapter Kit. Fits Kohler engine models KT17 Series II, KT19 Series II, MV16, M18,0 MV18, M20 and MV20. (Will not fit KT17 (first design) or KT19 (first design) engines because there is no provision on the block for an oil filter adapter.) Oil filter not included with kit; order separately (listed below). Having an oil filter helps the engine last much longer between oil changes by filtering out or removing small metallic wear fragments and contaminants from the oil that can cause excessive wear to the pistons, piston rings, cylinder walls, and especially the PTO end main journal on the crankshaft, resulting in low oil pressure, and possibly a burnt #1 connecting rod. Remember - Metal flake looks good in paint, not in oil. NOTE: Use the 1/8" NPT Allen pipe plug (Kohler part # 25 139 60-S) with kit on model M18 engines w/specification # 24532, after serial # 1835400002 (1988 and later) to block-off the hole in the adapter body if the engine is not equipped with a low oil shut-off sensor, oil pressure switch or oil pressure gauge.

  A-1 Miller's Professional Repair Service - Perform Valve Job Only on opposed twin cylinder Kohler KT-series and Magnum engine models KT17 (first design), KT17 Series II, KT19 (first design), KT19 Series II, KT21, MV16, M18, MV18, M20 and MV20. This service is for an engine that does not blow blue smoke out the exhaust and burn oil. Performing a professional valve job restores full compression, which allows the engine to start quicker, idle smooth without stalling, and it will have full power at top governed speed. Labor includes: regrind four valve faces and seats, lap in valves with valve lapping compound, reset valve clearances to factory specifications (on short block only), resurface both cylinder heads on a wide sanding belt to remove warpage and restore flatness, reinstall intake manifold and governor linkage. And being some valve guides wear beyond specifications, there will be an extra charge for installing and reaming new guides, if needed. The baffle shields (sheet metal), muffler, intake manifold and governor linkage will need to be removed before bringing or shipping engine/short block to A-1 Miller's shop. To save on shipping cost, only the cylinders (removed from the crankcase) and valves can be shipped in two 12-1/4" x 12-1/4" x 6" USPS Large Flat Rate Boxes. Place one box inside the other to double the strength, and use rigid packing material under, over and around/between the parts to prevent any of the fins from breaking off during shipment. But the short block must be shipped in a sturdy wooden crate. Or If you're the kind of person who don't trust delivery/shipping companies (mis)handling your high-dollar and fragile merchandise, you can make the long drive to A-1 Miller's shop to personally purchase parts, or drop off and/or pick up your carburetor, clutch assembly, engine parts, entire engine, transmission, transaxle, entire garden tractor, etc. for repairing and/or rebuilding.

''Round Up'' Crankshaft Rod Journal(s) and Resize Connecting Rod(s) - This service is for most makes and models of small engines when an undersize connecting rod or bearing inserts isn't available, if the crankshaft is worn beyond .010" and needs to be reground again, the journal can be reground to wherever it "cleans up" or is true again, then the connecting rod can be resized so it'll fit the smaller undersize journal with the factory recommended .0025" oil clearance. To resize the rod so it'll fit to a few thousands of an inch smaller diameter crank journal, first, metal is removed from the mating end of the rod cap, then the cap is fasten to the rod. The big hole in the rod is now oblong or "egg shaped." Then the big hole in the rod is honed until it's .002" larger than the diameter of the crank journal. Honing reshapes the hole into a perfect circle again, only smaller in diameter. This works very well and it lasts as long as an ordinary STD size rod and crank journal. This can only be performed on a rod with a good bearing surface. It cannot be done on a burnt or heavily scored connecting rod because too much metal would need to be removed. If you're interested, I will need your crankshaft and connecting rod(s). NOTE - The maximum a connecting rod can be resized to is .005" undersize. If it's resized more than .005", being the big hole in the rod will be made excessively oblong or egg-shaped, which will allow it to make less bearing surface contact around the crank journal after being resized, due to the centrifugal force at 3,600 RPM, the big end of the rod could become elongated (metal stretch) and might eventually knock and possibly break. NOTE: Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds. An innovative concept by Brian Miller, because nobody else advertise this service.

Small engine technology has changed a lot since the Kohler K-series and Magnum engines were made. I can rebuild your lawn and garden engine (or competition pulling engine) with new technological parts so it'll produce more power and last longer than the factory anticipated. I also build engines from scratch and rebuild customer's complete engines from factory stock, to 4,000± RPM governed, to wide open throttle Hot-Stock and Stock-Altered competition pulling engines. I can build a quality, competition engine for you, or rebuild your engine however you want. Just tell A-1 Miller's know how you're going to use your tractor or equipment and I'll build your engine to suit your needs. And if it's required in your association/club sanctioning engine rules or not, ALWAYS install a safety shield made of adequate thickness and material for each side of the engine fastened to the tractor frame securely in case of connecting rod failure (Murphy's Law), so an innocent bystander or spectator won't be injured or killed from high-speed projected metal shrapnel.
I don't have any rebuilt Kohler short blocks or engines in stock. And if I did, chances are, they probably wouldn't be designed for your garden tractor or equipment. Because Kohler engines are made specifically to fit a certain model of garden tractor or equipment. They are not a "universal fit" or "one fits all". Therefore, it'll be best to have your engines rebuilt instead. Then all the brackets, accessories and electrical wiring will reconnect to your garden tractor or equipment with no modifications.
Also, I set the air/fuel adjusters on all carburetors just so the engine will start and run, but because of the altitude level, barometric pressure and air temperature where the engine will be used, the customer will need to make the final bore.) OEM so the engine will run smooth. No carburetor with an adjustable high speed main fuel adjuster comes preset, not even new ones.
Furthermore, just to let you know, although I use the best parts, use caution on choosing the right motor oil to use in your engine. Because the government (tree huggers/Sierra club) is requiring oil companies to lessen the amount of zinc in their motor oils to reduce pollution. Zinc provides a protective coating on internal engine parts and prevents metal to metal contact for proper break-in and it helps the parts last longer. Many auto manufacturers and professional engine rebuilders are upset because of this too, because they have to guarantee their engines for a certain period of time, and many of them take pride in building their engines.
Regarding an Engine Build Estimate -
I am very meticulous in how I rebuild and build engines. If you would like to have A-1 Miller's build, rebuild or build-up your engine, I will need a detailed list of exactly what you want done to your engine or a copy of your association/club sanctioning engine rules and requirements regarding the engine requirements before I can give you an estimate on the cost. And if you (the customer), change your mind of how you want the engine built or rebuilt in the middle of a build, I will need to know ahead of time and I will need the changes in writing so I can make the necessary changes to the engine. Otherwise, this will effect how well the engine performs on the track, and it would make me, as a professional engine builder, look bad. It's not a good thing to be afraid that something bad may happen to an engine. Having confidence in an engine makes ya feel good, but having confidence in your engine builder makes ya feel better.
A-1 Miller's competition pulling engines will be coated with high quality gloss black paint (most common factory color), International Cub Cadet yellow paint, or the color of your choice. When you receive your engine, install the baffle shields (sheet metal), brackets and everything else on the engine, install the engine in the tractor, add motor oil to the proper level, install the fuel hose, add fuel, connect the ignition and starter wires, connect the throttle/choke cable controls, and the engine will be ready to start. Carburetor adjustments will be initially preset just so the engine will start and run, but due to the altitude level, barometric pressure and air temperature where the engine will be used, the final idle speed, idle air/fuel mixture and high speed air/fuel mixture adjustments will need to be made by the customer after the engine is started and warmed up to operating temperature.
Whenever I rebuild or build-up an engine, and if you would like to do so, I do whatever it takes so it'll produce the factory-rated horsepower or the maximum horsepower and torque, and last a long time. I go beyond what the repair manual says to do. I can get all the parts needed, too. I can build your engine so it'll be legal for the class you plan to pull in. And with my engine rebuilds and build-ups, you may not always win, but you'll look good trying! By the way - the surface of the exhaust area of a fresh-built engine may burn off the oil residue for a short time once it gets hot, but it'll stop after a while. It's nothing to worry about. This happens with most rebuilt engines, especially an engine with fresh paint.
I do not build illegal competition pulling engines that do not conform to your association/club sanctioning engine rules and requirements! But there are certain other engine builders that offer new pulling engines for sale. BUT, being different pulling associations/clubs have different engine rules and requirements, there is no "one pulling engine that conforms to each and every clubs' rules and requirements." Therefore, you may receive an engine that do not conform to your association/club sanctioning engine rules and requirements, and it may be built "above the rules". Meaning it's not legal within your association/club sanctioning rules and requirements and is illegal to run in the class you plan to pull it in (cheater engine). Or, the engine in question may be built "below the rules" so it's less competitive as an engine that is built to the max legally according to the rules and requirements. But I'll build your engine or an engine for you so it'll produce the maximum horsepower and torque in accordance with your association/club sanctioning engine rules and requirements, not less than what the rules and requirements allow. I also rebuild ordinary/stock lawn and garden equipment engines too, such as cast iron and cast aluminum block single- and twin-cylinder flathead, OHV and V-twin Briggs & Stratton, Kohler, Tecumseh and 2-cycle LawnBoy. I've never encountered an engine that I couldn't repair, rebuild or build-up/modify with more horsepower and torque!
FYI - Being I'm the only person to read and respond to all my customer's emails (about 20 or so per day), take my customer's phone call orders (about 20-30 on a nice day with good weather), with customers stopping by my shop, repair and rebuild my customer's parts and engines in my shop, locate hard-to-find engine parts, order parts from my suppliers, process orders, package parts then mail customer's parts at my local Post Office, etc., it may take A-1 Miller's several months to rebuild an engine. It also takes time to perform precision machine work and manual workmanship on an engine rebuild, especially for a competition pulling engine, and I wouldn't want to do a rush job. I also have to depend on other local machine shops to perform various machine work and balance rotating engine parts. All this takes time. I tried hiring different people to help me in my shop, but it seems a lot of people don't fully understand about most of the parts and services that I offer. I never fired anyone. They all quit on me. So please keep this in mind if you decide to have A-1 Miller's rebuild/build up your engine. Also, I don't like to rush on my customer's repair jobs. I'm very particular about my work, especially my engine builds. I like to take my time to make sure that everything is right, the engine will run right, produce full power and last a long time. I appreciate for you understanding my situation. - Brian Miller
FYI - Used OEM parts in good condition for older Kohler engines are hard to find now, especially the small parts. If the parts don't wear, they tend to get thrown away and then "engine scrappers" sell the parts that do wear on places like eBay. They don't think about people like me, who make a living by "piecing together" or building engines from scratch for a customer. I can purchase new parts from Kohler if they're still available, but that would be cost-prohibitive. I try to keep my engine builds at reasonable prices. - Brian Miller
All of A-1 Miller's customer's competition pulling engine builds are strictly confidential! This means the people you pull against will not know what goes into your engine.
Below Ê are details and prices to rebuild your engine -
  Professional Rebuilding Service for Briggs & Stratton 16, 18 and 20hp opposed twin cylinder aluminum block engine (horizontal or vertical shaft) professional rebuild to OEM factory specifications @ 3,600 governed RPM for general lawn and garden use or mild competition pulling. Only high quality replacement parts are installed! All baffle shields (sheet metal) will need to be removed before bringing or shipping engine to A-1 Miller's. When shipping an engine, it must be securely fastened inside a sturdy wooden crate. IMPORTANT: Click or tap here for proper break-in (wear-in) oils and procedure for rebuilt engines. NOTE: If your engine doesn't smoke out the exhaust and burn oil, then chances are, all it needs is a professional valve job performed. We can do this instead of rebuilding your engine. The price is $300.00 for all parts and labor to perform the valve job, plus return shipping.
 Professional Rebuilding Service for Briggs & Stratton Vanguard V-twin aluminum block engine (horizontal or vertical shaft) professional rebuild to OEM factory specifications @ 3,600 governed RPM for general lawn and garden use or mild competition pulling. Only high quality replacement parts are installed! All baffle shields (sheet metal) will need to be removed before bringing or shipping engine to A-1 Miller's. When shipping an engine, it must be securely fastened inside a sturdy wooden crate. IMPORTANT: Click or tap here for proper break-in (wear-in) oils and procedure for rebuilt engines.
A-1 Miller's Professional Valve Repair Service for Kohler Engine Model K361 Cylinder Head. This service is for an engine that does not blow blue smoke out the exhaust and burn oil. Performing a professional valve job restores full compression, which allows the engine to start quicker, idle smoothly without stalling, and (if the ignition timing and carburetor adjustments are set correctly, too), it will produce full power at top governed speed. Click or tap here for cylinder head bolt torque specs. And if you've ever wondered how the K361 rocker arms receive plenty of oil to keep them lubricated, when the engine is running at full governed speed, internal air pressure from the downward stroke of the piston forces crankcase oil through the pushrod tubes onto the rocker arms.
FYI - I found that the Kohler K361 18hp OHV cylinder head use the longer 1-3/4" (uncompressed length) valve springs with rotators, the same spring that certain K241, K301 and K321 use with a stamped retainer. And of course, certain K241, K301, K321, and all K341 use the shorter 1-9/16" spring with a rotator. The official Kohler parts manual says the K361 use the shorter 1-9/16" springs (with rotators), but apparently, it's wrong. It uses the longer 1-3/4" springs (with rotators). On all of the K361 engines that I've rebuilt, with the 1-3/4" springs and rotators installed, there is no coil bind. This is when the coils of the spring make contact with each other at full valve lift. I've had a customer send his K361 head to me for repairs, and when I spoke to him on the phone about his engine, he mentioned that the engine had always made a chattering/rattling sound at higher RPM and lacked sufficient power. He said he purchased the tractor used (with the same engine). So I checked the valve springs, and sure enough, it had the shorter ones (with rotators). Apparently, somebody (maybe the previous owner) worked on the cylinder head before, and for some reason, he installed the shorter valve springs. My customer was lucky it didn't drop a valve. That would've been a nightmare! But anyway, I installed a set of the longer 1-3/4" valve springs (with rotators). The valves felt stiffer when I pushed down on them with my hand, too. - Brian Miller Please contact A-1 Miller's if you're interested in purchasing any of the products or services listed in this website.

| Competition Pulling Engine Freshening Service [Top of Page] This service is for Kohler pulling engines only that have been previously built, and needs the basic parts and labor to revive the power. It is not a complete engine rebuild. A typical pulling engine will last an average of 25 pulls or 3 years of use. After that, the piston rings become worn, and the engine may lose power when under load and puff gray/blue smoke out the exhaust and/or crankcase breather vent. When this happens, it's time for a freshening job. If interested, we will need an updated copy of your association/club sanctioning engine rules and requirements so when the engine is freshened, it will be legal in its class, but still competitive. Click or tap here for proper break-in (wear-in) oils and procedure for rebuilt engines. Add $110.00 - $152.00 for installation of A-1 Miller's custom crank trigger or flywheel triggered electronic ignition system. (For competition pulling only.) A 50% deposit may be required on certain engine refresh jobs. Deposit is non-refundable if labor and machine work is invested in the engine, and parts are purchased for the engine.

Also included are: flywheel shroud (not chrome plated), aluminum or cast iron oil pan, bolt-on header pipe and conventional Kohler point ignition system installed with ignition timing preset. A-1 Miller's competition pulling engines will be coated with high quality gloss black paint or International Harvester Cub Cadet yellow paint. When you receive your engine, install it in the tractor, add motor oil to the proper level, install the fuel hose, add fuel, connect the ignition and starter wires, connect the throttle cable controls, and the engine will be ready to start. Carburetor adjustments will be initially preset just so the engine will start and run, but due to the altitude level, barometric pressure and air temperature where the engine will be used, the final idle speed, idle air/fuel mixture and high speed air/fuel mixture adjustments will need to be made by the customer after the engine is warmed up to operating temperature. Competition pulling engines will have no charging system. So use a high amperage 12 volt battery and a remote battery charger (with a gauge) to fully recharge the battery (preferably overnight) before each pulling event. And the only complaint we've received from our customer's concerning the pulling engines that we build for them is their tractor broke [factory stock] drivetrain and/or rear end parts. 4,000 RPM "Build to the Max" Stock-Appearing Competition Pulling Engines listed below - built for competition pulling only and to your pulling association/club sanctioning engine rules and requirements.

| Break-In (Wear-In) Oils and Procedure for Ordinary Rebuilt (Lawn and Garden) Engines - First of all, full synthetic/organic motor oil will allow an engine to run cooler and last longer. But the rule of thumb for different types of motor oils are: Full synthetic motor oil is mainly for high performance/racing engines that operate at high RPMs for a long time. Synthetic blend motor oil, which is a blend of about 50% organic and 50% petroleum, is for engines that occasionally operate at high RPMs, but also operate at normal speeds. And conventional/petroleum motor oil is safe to use just for engines that operate at normal speeds at all times. If the tractor is geared correctly, the pulling engines I build should not run out of power at the end of the pull. It should spin the tires. But there's some things that needs to be checked after a few pulls as the engine breaks-in and parts wear into each other. For gas fuels, the ignition timing needs to be set at 22º BTDC. And make sure the high speed air/fuel mixture screw is set so the engine runs smooth at high RPM. Also, if a high-output/performance ignition coil is used, it requires two standard capacity (Kohler) condensers/capacitors or one heavy duty, high capacity/performance condenser/capacitor. This is so the coil will produce more voltage. And with a high-output/performance coil, the spark plug gap can be set at .060". With an ordinary coil, it should be set at .035". The valve to lifter clearances may need to be reset at .010" for the intake and .014" for the exhaust. Furthermore, when a new or rebuilt engine needs to "break-in", what the term "break-in" actually means is the moving internal parts that make contact with each other needs to "wear-in" with each other so they'll produce a wear pattern and last longer. Any new or rebuilt engine, rather if it's for general lawn and garden use or for competition pulling, needs to fully break-in (wear-in) for it to produce full power. Rings don't "seat," they break-in (wear-in), or wear-in with the cylinder wall, and they wear-in quickly. But the valves are the parts that needs to "seat." Being the valve faces and seats have different angles (30º/31º or 45º/46º, respectively), the valve faces needs to wear into the seats to seal in the compression 100%. Wear-in will produce a 30½º or 45½º angle on both the matching valve face and seat. The harder material the valves are made of, the longer it takes for them to "seat" or wear-into the seats. Some pullers tell A-1 Miller's that the engines I built for them run better every time they pull them. I remember a few years ago when I performed a valve job on my truck engine. It ran good and produced plenty of power, but I noticed after about 1,000 or so miles, it produced a little more power. I realized that this is because the valve faces wore into the seats, forming a perfect seal. So again, a fresh-built pulling engine will not produce full power the first few times it's ran.

Garden tractor competition pulling engine technology has changed a lot through the years. We can rebuild your Kohler pulling engine with new technological parts so it'll produce more power, be more competitive on the track and last longer than anticipated. The engines listed below 
Break-In (Wear-In) Oils and Procedure for Fresh-Built Competition Pulling Engines - NOTES:
- A general stock engine rebuild includes: completely disassemble entire engine, degrease, clean and inspect all parts, bore (if it needs it) or deglaze cylinder, install new piston/rings/pin/clips assembly, regrind crankshaft journal (if it needs it), install new undersize (.010") connecting rod or bore rod for undersize bearing inserts (.020" or .030"; if it needs it), regrind valves and seats, install new gaskets with silicone sealer to lesson oil leaks, install new ignition tune up components, resurface cylinder head (on large disc sander or wide, flat belt sander) to remove warpage and restore flatness, clean and rebuild carburetor, clean commutator and lubricate bushings in gear starter and whatever else the engine may need so it'll run well and last a long time.
- The engines I sell are turn key engines. I build all engines according to the customer's personal preferences for non-pulling purposes or to the customer's pulling association/club sanctioning engine rules and requirements. "Build to the max" means engine will produce all the power possible and still remain stock-appearing externally. All of the above È will be performed in addition to the mild performance modifications.
- ± means more or less. This means if your engine needs minimal labor and/or machining, the price will be slightly less. But if it needs more than usual labor and/or machining, the price will be slightly higher. However, if it has sustained major internal damage or if it needs additional parts, extensive machine work and more labor, then the price will be even higher. And being I can't see your engine before you bring or send it to me, I can't honestly give an exact quote beforehand. But I'll treat you right and I'll try to keep the costs low as possible and still build you a quality engine so it'll start easy, produce full power and last a long time. The ± also depends on your personal preferences, parts needed and/or your pulling association/club sanctioning engine rules and requirements. Also, if you would like to provide some or all of the parts yourself, the price will be substantially lower.
- All rebuilt engines returned (shipped) to the customer come with a 90 day workmanship warranty from date of pickup or delivery.

Before shipping or bringing your engine to A-1 Miller's in person, I don't need everything on it. Just the parts that can wear and need rebuilding or reconditioning, such as the carburetor, fuel pump, gear starter, cylinder head and crankcase breather assembly. I'll need the oil pan on it too, to prevent any dust and dirt from entering the crankcase after the rebuild. I'll need the flywheel on the engine so I can set the ignition timing. Please remove all baffle shields (sheet metal) and the PTO clutch assembly, too. By the way - I can rebuild the Cub Cadet mechanical PTO clutch, too. I have a heavy duty 2-jaw gear puller that we use with a large C-clamp to remove/pull off the mechanical PTO clutch/pulley assembly from engines out of an IH Cub Cadet garden tractor. But sometimes these clutch/pulleys will not remove without breaking. I do all I can to try to prevent this from happening, but when they do break, I have no choice but to install a rebuilt PTO clutch/pulley assembly. I also made a special puller tool to remove the stamped steel PTO pulley/basket from the crankshaft without damage. Regular shop hours are 9:00 am - 5:00 pm, Monday-Friday. And we're open on weekends by appointment only. Please call, text or email me before coming so I'll be at my shop waiting for your arrival. If you are traveling a great distance, it's best to call in advance (573-256-0313 (shop) | 1-573-881-7229 (cell; text or when leaving a voice message, please speak slowly and clearly) to make sure that I will be here when you plan to stop by. Please ship or bring your engine when you're ready to the address below. Ê
If shipping an engine, and if the crated engine weighs no more than 150 lbs., use only Fastenal or FedEx Ground for dependability. The average crated cast iron block Kohler engine weighs just under 150 lbs. Use this website to calculate the shipping cost for your engine: FedEx Rates and Transit Times. Contact your local Fastenal or FedEx Ground shipping center for more details and to schedule a pickup or drop off the crated engine at your local Fastenal or FedEx Ground shipping center. Fastenal and FedEx Ground are the only reasonably-priced shipping service that I know of for items up to 150 lbs. US Mail only ship up to 70 lbs. And FedEx Freight would cost almost as much as an engine is worth. If your engine is too heavy to go with FedEx Ground, partially disassemble it and send the lightweight parts in a USPS Large or Medium Flat Rate Box, and then send the main short block with FedEx Ground, the crated engine can be shipped through Fastenal. This also works better to save money on shipping costs. You can visit A-1 Miller's shop to drop off and pick up your engine(s) to save on crating and shipping charges.
When the work is completed, I'll contact you with the total including return shipping & handling. For payment options for parts ordered or services performed, or to make a donation to my websites, I accept cash (in person), USPS Postal Money Orders, cashier's checks, business checks, MasterCard, VISA, Discover, American Express (please add 2.5% to the total for the credit/debit card processor's surcharge), Western Union Money Transfer or MoneyGram Money Transfers. (If the engine is for a specific purpose and parts must be special ordered, full payment will be required right after your order is placed or your debit/credit card will be charged for the full amount or as a deposit.) Or you can pay A-1 Miller's through PayPal. My PayPal account name is my email address, and be sure to mention in PayPal a description of what the payment is for. If sending a money order or cashier's check, please include a note in the envelope with your name, complete mailing address, phone number and a description of what the payment is for. My mailing address and phone number are below Ê. And I will ship your rebuilt engine/parts to you as soon as I receive your payment.
To ship a transaxle, this is easier. They don't require an enclosed crate. Just place the transaxle on the center of a shipping pallet (of the appropriate size) and stretch wrap (use low-cost ratchet nylon tie-downs) to securely fasten it to the pallet. Use at least 6 layers of stretch wrap or several tie-downs. This should work really well. The shipping weight of a Cub Cadet cast iron case transaxle when strapped to a wooden pallet is approximately 215 lbs. [Return To Previous Paragraph, Section or Website]

Payment Options and We Ship to Canada and Worldwide 
Item(s) in a package or cushioned envelope weighing less than 1 lb. is sent by US Postal Service Airmail Letter Post for a 4-7 days delivery. Packaged item(s) weighing over 1 lb. and up to 66 lb. is sent by US Postal Service Airmail Parcel Post for a 4-10 days delivery. I cannot use the US Postal Services' Flat Rate Priority Mail envelopes and boxes to ship outside U.S. territories. Item(s) weighing over 67 lbs. or more is sent by FedEx Ground or equivalent services. We try to keep our shipping cost to customers within reason. Therefore, we don't ship our products in a fancy-looking package with our company name and/or logo on it because most customers will just toss it in the trash after they remove the contents. And being there is no USPS tracking number outside the US, all I can do is make sure I write your address correctly on the customs form and on your package.
My websites are not set up to process orders and accept payments. Therefore, for payment options, I accept cash (in person), USPS Postal Money Orders, cashier's checks, business checks, MasterCard, VISA, Discover, American Express (please add 2.5% to the total amount for the credit/debit card processor's surcharge), Western Union Money Transfer or MoneyGram Money Transfers. If paying with a credit/debit card, please call me at either number below. To make a payment to me through PayPal, please click this link: https://www.paypal.me/PullingTractor. Please use the "Friends and Family" option, or add 3% to the total amount to cover PayPal's processing surcharge.
