A-1 Miller's is an Authorized OEM Kohler Engine and Parts Dealer!

Small Engine Parts and Repairs, Custom Garden Tractor Pulling Parts, Engines and Machine Shop Services | Offering Quality Products and Professional Workmanship at Reasonable Prices!

Everything in this web site is up-to-date and still available. Updates are made only when there's a change of a listing for a part or product. If a part or product is no longer available or have been discontinued, I remove it. I shop around for high quality parts and try to find the most reasonable prices available, so prices are subject to change without notice. I can also get a lot of other parts that's not listed on my web sites. Just let me know what you need and I'll see if I can get it at a reasonable price. And the condition of these parts are brand new, first line products, unless otherwise stated. No seconds or blemishes being pawned off on unsuspecting customers. Optimized for 1024 x 768 screen resolution. To search for a word or phrase in any of my web sites, with Internet Explorer 6.x, or Google Chrome, press CTRL+F to open the Find dialog box.

FYI - I'm not an OEM Cub Cadet parts dealer. Cub Cadet won't let me become a dealer because there's already one in my area. (It's another way how big businesses support other big businesses, or how the rich help the rich get richer.) Besides, competition from different dealers in the same area help keep prices low. I think this is unfair business practice because by allowing only one dealer in a wide-spread area can have them gouge (overcharge) unsuspecting customers on parts and/or repair costs. They probably laugh all the way to the bank after every sale, too.

NOTE: To place an order, please call the number or send an email (below Ê) with a description of the parts, products or services you need including your zip code and I'll respond with the total amount with shipping & handling. Because as of now, my web sites are not set up to accept orders. And I apologize, but I have no printed material (catalog) available at this time. You'll have to print out my web sites. I contacted some book publishing companies and they said being all my information is online at no charge, they don't think the books would sell well.

"Perfection takes time. If it's worth having, it's worth waiting for." - Brian Miller

We have a mail-order garden pulling tractor parts and repair service business, and we offer small engine repairs, various garden tractor pulling parts and repair services, various Cub Cadet parts, sharpening service, steel welding and general machine shop services. Will do our best to fix anything and everything. We have a well-equipped machine shop, so there's not much we can't do.

We are very particular about our repairs and the quality of the products that we offer for sale. We fabricate and use the same quality parts that we sell to our customers in our personal lawn & garden equipment and pulling tractors. Nothing less. Because if we don't feel comfortable or satisfied about a certain part that we make or sell, then we know you won't either. We also offer honest and reliable repairs. We won't sell you parts or services you don't need. And we've always been a "green" company! We reduce, reuse, recycle and restore when others just "throw it away." In other words, we'd rather repair an old part than replace it with a new one.

If you have a request, needs or questions concerning machine work within our facility's capabilities, please give us a call at the number below Ê during regular business hours.

Carburetor Gaskets | Carburetor Parts | Throttle Cable Clamps, Linkages and Governor Springs | Fuel System Parts | Fuel Pumps | Air Filters | Carburetor Rebuild Service, and New, Rebuilt and High Performance Carburetors for sale

NOTE: All parts listed here are NEW, unless otherwise stated. I do not sell cheap junk! As a matter of fact, many of the OEM Kohler K-series and Magnum engine parts are still made in the U.S. The Kohler Courage engines and parts are made in China. As a matter fact, Kohler owns two factories in China that make the parts. And most aftermarket parts listed in this website are also made by Kohler to Kohler's strict specifications. Kohler just place the part(s) in a generic box and sell them for less money. So when purchasing a genuine OEM Kohler part that comes in a box with the Kohler name on it, you're really just paying more money for the name on the box. And as far as some parts being no longer available - either the parts didn't sell well or the EPA is trying to phase out parts for the old cast iron block flathead engines because they produce more air pollution than the newer OHV engines.

To adjust the float level, use a small flat screwdriver to gently bend the tang that contacts the float valve. Then make sure that the float moves up and down freely without binding.

NOTE: The bottom adjuster is not an OEM Kohler part or a modification from Kohler. It's an "add-on" feature for competition pulling engines that run at very high rpms or at wide open throttle to prevent the high speed needle adjuster from enlarging the main jet hole due to normal engine vibrations. A carburetor must be converted to the bottom adjuster when using this part.

Drilled for gas. This part is professionally CNC machined in the USA and not available from Kohler. (Originally designed and made by the Carter Carburetor Corporation.) NOTE: When rebuilding a plain, stock Carter/Kohler carburetor, there is no need to remove the main jet/nozzle. If it won't come out, then don't worry about it. All that has to be done to make sure the bottom hole and the side holes on it are open. To check if the side holes are open, simply spray carburetor cleaner or WD-40 or carburetor cleaner (in an aerosol spray can) through the small hole just under the choke plate and observe if the spray exits out the main jet/nozzle inside the throttle bore and bottom of carburetor. But if modifying a carburetor to bore the venturi, the main jet/nozzle must be removed. Click here for how to remove the main jet/nozzle.

High Speed Main Fuel Mixture Needle Adjuster Screws for Carter #16, #18, #20, #22 Carburetors. (Originally designed and made by the Carter Carburetor Corporation.) NOTE: Certain high speed main adjusters are designed for a particular carburetor. I list the part number of the carburetor to match the type of adjuster it requires. Kohler don't give their dealers much information on this. I did some research, and I have several used carburetors in stock, and compared the type of adjuster to the part numbers on the carburetor and found that some are in fact different. The number of holes midway on the high speed adjuster allows a small amount of air to be mixed with fuel through the idle circuit so the engine won't idle too rich or too lean on fuel. And the absence of holes midway allows full flow of fuel through the idle circuit, which when used in the wrong carburetor, may cause an engine to idle too rich on fuel. So if an engine idles well (with the present adjuster), then the carburetor has the correct adjuster. Also, being the high speed adjusters are made of soft brass, if the pointed tip of an adjuster is slightly bent, it can be easily straightened with pliers and reused, and will not effect engine performance whatsoever. And if the tip is not exactly centered with the hole in the main jet/nozzle, this will also not effect engine performance whatsoever. But if it's damaged from being overtightened, it will need to be replaced.

A worn throttle shaft is the #1 cause of most engines wearing out and burning oil prematurely. If a carburetor has a worn throttle shaft, this will create a vacuum leak and the engine will idle poorly, if at all at times. Not to mention the engine will also draw in dirty air, causing wear on the valve faces/seats and piston rings, and engine will burn oil. More than .010" of play is considered too much for throttle shaft wear. Plus, at operating running speeds (3,600 rpm), the extra air will cause the engine to run lean on fuel, which will overheat the combustion chamber and cause the cylinder head to warp (blow a head gasket) and the piston and rings to wear prematurely, eventually resulting in severe engine wear and excessive oil burning. Along with regular maintenance, repair of a worn throttle shaft is required to help an engine last a long time. The most accurate way to check for amount of wear is with a dial indicator.

Furthermore, the Carter/Kohler or Walbro carburetors don't come with a throttle shaft bushing installed from the factory. A bushing (see below Ê) must be installed when the throttle shaft is worn, or a bushing and new throttle shaft both must be installed. If there's a counterbore where the throttle shaft is, a flat bronze bushing can be installed, and if it's in good condition, the original throttle shaft can be reused. But if there's no counterbore, the carburetor body will need to be precision aligned-bored for installation of a bronze sleeve bushing, and chances are, a new throttle shaft will also need to be installed. Special machining of the carburetor body is required for the sleeve bushing.

Bronze throttle shaft bushingThrottle Shaft Bushing for Carter #16, #18, #20, #22 carburetors with a counterbore that's used on Kohler engine models K90 (3.6hp), K91 (4hp), K141 (6¼hp), K160 (6.6hp), K161 (7hp) and K181/M8 (8hp), as well as other makes and models of engines that use the Carter #16, #18, #20, #22 carburetor. Dimensions: .213" i.d. x .407" o.d. x 1/8" height. NOTE: Some very early Carter carburetors have a smaller diameter throttle shaft, which is .213" or #3 [drill bit]) size. The bushing offered here is made for the smaller shaft. If a carburetor has the bigger 7/32" (.219") shaft, once installed, the bushing will need to be carefully drilled or reamed larger to 7/32". Also, some later Carter carburetors do not have the counterbore to accept this bushing. If there's no counterbore, then if the shaft hole is not severely worn, a new throttle shaft (see below Ê) can be installed. Go here to learn how to professionally remove Carter/Kohler throttle or choke plate retaining screws. But if the shaft hole is severely worn, it will need to be enlarged slightly to match an oversized fabricated throttle shaft. The lever will need to be ground off the off shaft and welded onto the new shaft. I offer this service, too. (see below Ê) No Kohler part number.

Please contact me if you're interested in this repair service. An innovative concept by Brian Miller, because nobody else advertise this service.

Installation Instructions: If it isn't severely worn, the original throttle shaft can be reused with the above È bushings. The bushing makes contact with the upper unworn 1/8" area on the shaft. To install the bushing, remove the two small brass screws that secures the throttle plate to the shaft, then remove the shaft from the carburetor body. Clean out the counterbore and depending on the size of carburetor, use a 3/16" or 1/4" bolt and small hammer to squarely drive the bushing into the counterbore, and then reinstall the shaft. Additional Note: Usually the short, flat bronze bushing will snug up a worn throttle shaft. The bushing should last a long time, too. If the bushing fits somewhat loose in the counterbore, tap the sides of the counterbore with a hammer to close it up slightly. In other words, make the counterbore slightly oblong or egg-shaped. But don't mash the metal in too much. Just a slight tap on either side should do. But the newer Walbro carburetors have no counterbore for the bushing. Therefore, sometimes the throttle shaft hole in the carburetor body will wear, too. When this happens, installing a new shaft won't fix the problem. The hole must be accurately bored and a bronze sleeve bushing will need to be installed with a new shaft, or if the hole is not worn, sometimes the original shaft can be reused. But if the original shaft is worn and a new throttle shaft isn't available for a particular carburetor, then one must be machined from scratch. And if necessary, a slightly oversized shaft can be installed instead of the original diameter shaft. I can do this for $50.00 parts and labor, plus return shipping & handling.

Throttle Shaft Sleeve Bushing for the newer Walbro WHG #52, #60, #64 carburetors that have no counterbore for the short throttle shaft bushing, or for the Carter/Kohler carburetor with a worn counterbore for the short throttle shaft bushing. Dimensions: 1/4" i.d. x .313" o.d. x 3/4" long. NOTE: The upper throttle shaft hole must be precision-bored exactly to .3125" (5/16") in perfect alignment with the lower hole for installation of this bushing. Apply clean motor oil on throttle shaft before installing for smooth throttle action and less wear to shaft and bushing. Not to be used in the Kohler-made carburetors for Kohler engine models K482, K532 or K582. An innovative concept by Brian Miller, because nobody else advertise the use of this part or this service.

  • Repair Service: Bore upper throttle shaft hole, install new bronze sleeve bushing. $45.00 labor and bushing + price of new throttle shaft with new screws/lock washers (if needed), plus return shipping & handling. An innovative concept by Brian Miller, because nobody else advertise this repair service .

If the throttle shaft holes are worn in a K482, K532 or K582 carburetor, if the holes aren't worn beyond for reuse, I just use 1/4" cold rolled steel to make a new throttle shaft. But if the holes are worn, and being the metal is too thin on one side for installation of a bushing, the holes will need to be enlarged a few thousandths bigger than 1/4", and a steel rod that's slightly bigger than the enlarged holes (for a slip-fit) will need to be fabricated for use as a throttle shaft. I then align and weld the OEM throttle lever to the new shaft. I've performed this type of repair many times with excellent results. I offer this repair service. If interested, for dimensional measurements, I will need the complete carburetor with the throttle shaft/lever and throttle plate. FYI - Bearing bronze is very hard, porous, absorbs oil and lasts a long time when lubricated regularly and used as a bushing. Brass, on the other hand, is soft, non-porous and wears quickly when used as a load-bearing bushing or shaft. An innovative concept by Brian Miller, because nobody else advertise this service.

Includes everything shown in picture. Kit includes OEM Kohler throttle shaft part # 47 144 36-S, brass idle adjustment screw and compression spring. NOTE: The protruding pin will need to be ground flush with top of carburetor body and a 9/64" or #29 (drill bit size) hole will need to be drilled through carburetor body and 8-32 NC threads cut for installation of the idle speed adjusting screw. And apply clean motor oil on shaft before installing for smooth throttle action and less wear to shaft, bushing or carburetor body.
  • $25.00 per kit, plus shipping & handling.
NOTE: If an OEM Kohler throttle lever has a ball/stud pressed on it, and if the same throttle linkage is going to be reused, the ball/stud will need to be transferred to the new lever by grinding away the flared metal underneath and then place a small bead of weld under the ball/stud to secure it in place on the new lever. Or a new ball w/threaded stud that's listed in this web site can be purchased from me. Also, the holes in the OEM Carter/Kohler [steel] throttle plates, which have an 11/16" spacing for the #26, #28, #30 carburetors, will need to be slightly elongated with a Dremel or equivalent small grinder to match the holes in the 47 144 36-S Walbro throttle shaft, which have a 3/4" spacing. And when installing either throttle plates, with the carburetor float area facing downward, install the plate with the stamped numbers or letter(s) facing outward and toward the right of the throttle bore (as shown above È). And use split lock washers with throttle and choke plate screws to prevent screws from loosening and possibly becoming lodged in intake valve or on top of piston, which could cause severe damage. This is why I recommend using them. Liquid threadlocker is not required with lock washers.

Remote Carburetor Fuel Primer Kit. Safe to use and works flawlessly! The primer bulb system squirts gas through the main jet/nozzle, causing a slight flooding condition in the carburetor throttle bore so a cold or hard-to-start engine will start easier. Just a couple of pushes of the bulb and the engine should be ready to start. Cannot over-flood an engine like the choke plate can. Replaces the choke plate/shaft. For ordinary garden tractors, garden pulling tractors or virtually any type of small engine lawn and garden equipment. Works with pump gas or alcohol fuels. Kit includes primer bulb assembly w/mounting nut, 3' of 1/8" i.d. clear vinyl hose and 1/8" x 1" brass tube (to install on side of carburetor for new atmospheric vent hole; original vent hole(s) must be plugged). An innovative concept by Brian Miller, because nobody else advertise this kit.

Will work for most single- and twin-cylinder gas engines such as Kohler, Briggs & Stratton, Tecumseh, Wisconsin, etc., on virtually all models of Cub Cadet, John Deere, Wheel Horse, Sears Suburban, Massey Ferguson, and just about any lawn & garden equipment with a 12 volt electrical system. Alcohol resistant and very durable. For stock engines or engines running at wide open throttle. Suitable for small gas engines up to 4 cylinder carbureted engines. Instant fuel prime to the carburetor as soon as pump is powered up. Ideal when equipment runs out of gas and no need to crank engine for a long time to refill carburetor to restart engine. Saves on starter motor wear. Operates on 12 volts DC. Rather than a motor or diaphragm, this solenoid pump uses a piston actuated by an electromagnetic coil to generate fuel pressure and flow. By using only short pulses of electricity, this pump is very efficient. Kit includes: fuel pump, mounting bracket w/bolt/nut, two 1/4" barbed fuel hose fittings, 12" of 1/4" i.d. reinforced fuel hose and fuel filter. Click here for electric fuel pump installation diagram. IMPORTANT: As with any electric fuel pump, to prepare for long-term storage, drain and flush out all fuel, and fill inside of pump with light oil to prevent oxidation and possible sticking of internal moving parts.

Professional Carburetor Rebuilding Service - Top of page | Please contact me if you're interested in any of these parts or services.

FYI: We can professionally rebuild older vintage and antique carburetors virtually of any kind as well as newer ones, as long as replacement parts are available. We also have the capability to fabricate new throttle and choke shafts. Please contact me if you have any questions.


Carburetor Repairs and Complete Rebuilds - YOUR 10hp-18hp Carter/Kohler or Walbro carburetor: FYI - Many of my customers send me their carburetors for rebuilding, but lots of times I couldn't find anything wrong them. So I'd call my customers just before returning their carburetor asking how their engine acted. And after hearing their story, I told them that their engines might need a valve job performed instead. And lo and behold! Many of them either adjusted the valves or had a professional valve job performed and said that their engines ran like new. I'm not saying this happens with all engines, only the majority of them.

Repair or Rebuild YOUR Carburetor -

Modifications for the 10-18hp Kohler CarburetorBasic rebuild with no "high-performance" modifications whatsoever, according to the condition of the carburetor, the repair price is minimum $55.00 for parts and labor, plus return shipping & handling. This includes complete disassembly of carburetor, ultrasonic cleaning of the carburetor body and attached parts, repair worn throttle and/or choke shafts (if necessary), and install new overhaul kit. Any additional parts or services are an extra charge. Work includes whatever parts and services it may need that's listed below Ê.

Work Includes:

ü Completely disassemble and ultrasonic clean carburetor body and attached parts.
ü Resurface mounting flange and choke end to remove any warpage to prevent a vacuum leak.
ü Enlarge the lower hole on the high speed needle adjuster so engine will start quicker and idle better. An innovative concept by Brian Miller, because nobody else advertise this repair service.

ü The idle speed and air/fuel mixture adjustments will be preset on the carburetor to get the engine running, but due to the altitude (atmospheric pressure) where the engine will be used, the final adjustments will need to be made by the customer or an experienced small engine mechanic/technician or an experienced small engine mechanic/technician so the engine will run smooth.

IMPORTANT: When sending your carburetor to me, please package it securely so it won't get damaged in shipping and include a note in the package with your name, complete and correct postal address, phone number (in case we have any questions), a description of what you want done and any other parts you may need. And be sure to enclose it in a sealed zip-lock sandwich bag to prevent the odor of gas from escaping the package. If the odor of gas can still be smelled, apply perfume, cologne or Febreze® on the carburetor to disguise the smell of gas. Because the US Postal Service or other delivery services will not deliver any packages that smell like gas. And we'll call or email you when it's repaired.

The 48 053 11-S carburetor is designed specifically for the K582 engine and if a carburetor with a smaller throttle bore is used, the engine will not produce as much power.

  • Rebuilt. $200.00 each, plus shipping & handling. (When available.)
  • New. $412.05 each, plus shipping & handling.

NOTE: If the throttle shaft holes are worn in a K482, K532 or K582 carburetor, if the holes aren't worn beyond for reuse, I just use 1/4" cold rolled steel to make a new throttle shaft. But if the holes are worn, and being the metal is too thin on one side for installation of a bushing, the holes will need to be enlarged a few thousandths bigger than 1/4", and a steel rod that's slightly bigger than the enlarged holes (for a slip-fit) will need to be fabricated for use as a throttle shaft. I then align and weld the OEM throttle lever to the new shaft. I've performed this type of repair many times with good results. I offer this repair service. If interested, for dimensional measurements, I will need the complete carburetor with the throttle shaft and throttle plate. The repair price per shaft is $75.00 for parts and labor, plus return shipping & handling. Please contact me if you're interested in this repair service.

Rebuilt, reworked and modified only for high performance use, #26 Carter/Kohler carburetors. The venturi in these carburetors can be bored so they'll have either a 7/8", 1" (.995" NQS legal) venturi or a 1.07" straight-through throttle bore for high rpm operation, setup for gas, E85 or methanol fuels, whatever your club's sanctioning rules allow or whatever you desire for all-out engine performance. These carburetors are completely disassembled, then thoroughly cleaned. All fuel passageways cleared, new parts and if necessary, a new throttle shaft and/or bushing are installed. The idle speed and air/fuel mixture adjustments will be preset on the carburetor to get the engine running, but due to the altitude (atmospheric pressure) where the engine will be used, the final adjustments will need to be made by the customer or an experienced small engine mechanic/technician so the engine will run smooth.

NOTE: These carburetors are designed for use on Stock, Hot-Stock, Stock-Altered or Missouri Super Stock pulling engines with a stock size or an oversize intake valve. Also, a high performance carburetor is designed solely for a high performance engine. Just bolting on a high performance carburetor is not how to gain more power and torque for a stock engine. If your engine is not a high performance engine built to race specs, then it will not benefit from a high performance carburetor whatsoever. These carburetors will not allow a stock "factory-built engine" to produce lots of power just by bolting it it on. Everything in the engine MUST work together to prevent air restriction or a "bottleneck" to slow down air flow. With a bigger carburetor, the engine needs to breath A LOT more air in and out of the combustion chamber. This means the intake and exhaust ports will need to be made bigger, the valves reworked for more airflow, a bigger cam will need to be installed, and the ignition system will need to be up to standards.

Also, these carburetors are "built to order." So when placing an order, please specify if your engine has a factory stock size or oversize intake valve, if you want it with a straight-thru throttle bore (no venturi) or a 1" (.995" NQS legal) venturi, if the engine is going to turn at 4,000± rpm, high rpms or at wide open throttle, and if you want the choke plate/shaft installed.

All rebuilt carburetors that we service and sell come with a 30 day workmanship warranty and are guaranteed to be free of defects.

And I sell our clutch parts individually for the do-it-yourself rebuild. Also, I don't sell complete clutch assemblies because I don't have enough parts to put them together. But I can rebuild your clutch assembly, if you don't mind sending it to me. I can rebuild your clutch assembly however you want. Just tell me how you're going to use your tractor and we'll build your clutch to suit your needs.


Driveshafts for IH and MTD-built Cub Cadet models 70, 71, 72, 73, 86, 100, 102, 104, 106, 108, 122, 124, 126, 128, 580, 582, 800, 1000, 1050, 1200, 1604, 1606 and 1806. Spiral pins sold separately. (Scroll down). NOTE: These driveshafts are made to order. When ordering, please specify the model of Cub Cadet you have and possibly the exact length and where you want the roll pin holes drilled. If you're not sure about the length, to determine the exact length, measure between the end of the crankshaft threads or bolt head to the input shaft on the transaxle (or creeper drive input shaft), and then subtract 1/4". This will allow an 1/8" clearance on each end. I also make driveshafts for hydrostatic drive Cub Cadets. Ê

Replacement Driveshaft Spiral Pins. Each made of hardened carbon steel. Minimum Rockwell hardness is C42. Pins are heat treated. NOTE: The driveshafts with or without a creeper drive unit use the same number of spiral pins. There's two for the pressure plates, one at the end of the main pressure spring, and two in the rear coupler.

New machined aluminum clutch disc with (6) 13/32" drive holes for a 3- or 6-pin drive plate. This is a direct replacement for Cub Cadet's OEM fiber clutch disc. Made of the highest quality 6061 alloy; medium-grade hardness aluminum available. The edge of the disc is turned true in my metal lathe, then the 6 holes are precision-drilled using my milling machine in an 8" super spacer with a 6-notch masking plate. Unlike the competition that offer the same copycat part, the drive holes in my aluminum discs are drilled to 13/32" to reduce clutch rattle and less chance of breakage to the drive pins.

IMPORTANT - Both pressure plates MUST be resurfaced until perfectly flat and trued-up (to reduce vibration) in a metal lathe or severe clutch slippage may result!

Center drive plate (floater/disc) for double OEM fiber clutch disc setup. Made of mild steel. Trued-up in my metal lathe. Dimensions: .133" thickness x .626" center hole x approximately 4-1/2" diameter.


Your Cub Cadet drive clutch pressure plates professionally resurfaced until perfectly flat and trued up in my metal lathe. FYI - OEM Cub Cadet steel pressure plates are stamped in a large press and not machined in a lathe from the factory, which makes them oblong (egg-shaped) and not perfectly flat. Oblong (out of balance) pressure plates will cause the bronze pilot bushing to wear and the driveshaft to break at high rpms. And pressure plates that's not perfectly flat will cause the clutch to slip.

Used OEM Cub Cadet drive clutch pressure plates, professionally resurfaced until perfectly flat and trued up in my metal lathe. Replace deep-pitted rusted, severely worn or bent pressure plates.

If you want to use either of these plates in a "Quiet Line" ISO-mount tractor (models 800, 1000 and 1200), then a set of my solid motor mounts must also be installed. OEM Cub Cadet part # IH-384652-R12.

  • Used. $60.00 each, plus shipping & handling. (When available.)
  • (Cub Cadet dealer: $130.00± retail!) FYI - I'm not an OEM Cub Cadet parts dealer. Cub Cadet won't let me become a dealer because there's already one in my area. (It's another way how big businesses support other big businesses, or how the rich help the rich get richer.) Besides, competition from different dealers in the same area help keep prices low. I think this is unfair business practice because by allowing only one dealer in a wide-spread area can have them gouge (overcharge) unsuspecting customers on parts and/or repair costs. They probably laugh all the way to the bank after every sale, too.

The IH Cub Cadet "Original" Clutch Assembly - | Please contact me if you're interested in any of these parts or services.

An engine that runs at high rpms or at wide open throttle, the bronze bushing in the IH Cub Cadet "Original" clutch disc/pulley will not last long under side-thrust. Therefore, it'll be a good idea to have two sealed, high speed radial ball bearings installed in the clutch/pulley disc. See the picture below Ê for a better understanding.


The drive belt for an IH Cub Cadet "Original" is part number IH-376230-R1, the size is 3/8" wide x 31-1/2" long and it retails for about $12.00 (as of 3/21/12).

Conventional Ignition Parts - | Please contact me if you're interested in any of these parts or services.
Ignition points used on Kohler K-series engine models K90/K91, K141, K161, K181, K241, K301, K321, K330/K331, K341, K361, KT17, KT17II, KT19, KT19II, K482, K532 and K582. Also replaces Tecumseh: 32011, 32011A used on 6-20hp engine models HH80, HH100, HH120 series with battery ignition; Clinton engine models 414, 418, 420, 422. Each comes with mounting bracket. NOTE: Apply oil or grease on the hinge pin before installing points so the hole will last longer. When it's dry, it'll wear prematurely, effecting ignition timing, resulting in loss of engine power. Kohler part # 47 150 03-S.
  • High quality aftermarket. $9.00 each, plus shipping & handling.
  • OEM Kohler part. $14.30 each, plus shipping & handling.
  • NOTE: The NOVA II, Mega-Fire or OEM Kohler Solid State Modules (below Ê) can be substituted for the points and condenser for a hotter and more stable spark, and virtually trouble- and maintenance-free magneto ignition system.
Chevrolet (GM) V8 adjustable ignition points that can be used on the Kohler K-series 10hp-16hp and twin cylinder flathead cast iron block engines. NOTE: The "Chevrolet" points and condenser are actually made for the 1955-1974 General Motors cars and trucks with a V8 engine and Delco-Remy distributor. But these points can be easily adapted for use on Kohler [pulling] engines with an adapter bracket for easy adjustment of the ignition timing with an Allen wrench. Points have a stiff spring for quick response at high rpm. Due to the inability to completely seal (cover) the point contacts from dust and debris, these are for competition pulling only, and not for general yard and garden use. And being the bracket for the GM points and the GM points themselves are much larger than Kohler points and bracket, the OEM Kohler points cover will not fit over the GM points and bracket.
  • Points only; does not include bracket. $10.00 each, plus shipping & handling.
  • For Chevy points mounting bracket and protective cover, contact Midwest Super Cub or Lakota Racing.
Standard capacity BATTERY ignition condenser used on Kohler K-series engine models K90/K91, K141, K161, K181, K241, K301, K321, K330/K331, K341, K361, KT17, KT17II, KT19, KT19II, K482, K532 and K582.

Magneto Ignition Coil. Fits certain Kohler engine models K141, K161 and K181 with coil mounted on U-shaped stator on bearing plate underneath flywheel with rotor (rotating magnet) on crankshaft. Will also fit certain larger cast iron block Clinton engines with coil mounted above flywheel, on cylinder. Spark plug wire not included. Dimensions: 1.750" diameter x 1.450" length x .505" square hole. NOTE: The NOVA II, Mega-Fire or OEM Kohler Solid State Modules (below Ê) can be substituted for the points and condenser for a hotter and more stable spark, and virtually trouble- and maintenance-free magneto ignition system.
  • OEM Kohler part # 231718-S. $133.35 each, plus shipping & handing.

NOTE: The magneto coil wrapped with varnish-coated paper (Kohler part # 210293), and the stator assembly and rotor shown above are no longer available from Kohler. If you have an engine without these parts and you can't locate them from any source, your only option is to convert the engine to the battery ignition system. A small motorcycle battery or a rechargeable 12 volt sealed lead acid (SLA) battery with a minimum 4AH (Amp Hour) rating will need to be required to power the ignition, and with no charging system, a portable battery charger will need to be used to keep the battery fully charged when the tractor is not in use so the ignition will produce a hot spark. Avoid using a high-output/performance coil because these draw more amps from the battery.

Magneto Ignition Coil for engines with point/condenser ignition. For Kohler K-series flathead cast iron block, most smaller aluminum block Tecumseh and Clinton engines with coil/stator under flywheel. Replaces Tecumseh part #'s 29632, 30546, 30560, 30560A, 610768; Tecnamotor # 1633.0001; Kohler #'s 220435-S, 47 145 02-S, 47 755 20-S; Clinton # 135-13-990 and Phelon # FG-6240. Spark plug wire molded in coil. Spark plug wire length: 17". NOTE: Usually, the point gap sets at .020", but sometimes it will need to be set as close as .015" just to get a spark. This coil will work even better when used with the NOVA II, Mega-Fire or Kohler modules (see below Ê). The short wire on the coil is for ground, the longer wire connects to the points and condenser, and may need to be made longer depending on your application. Click here for identification and wiring diagram for this coil. Dimensions: .400" x .400" square hole (across flats) x 1.630" o.d. x 2.020" length (including spark plug wire hump). If laminations on your stator are too big for the hole in this coil, they can be ground or filed smaller so coil will fit snug, then bend one laminate over to retain coil, or if the laminations are too small, thin strip(s) of steel can be added so coil will fit snug, and coil should produce a hot spark. The coil must fit snug on the laminations to receive the full effect of the magnetic field through the stator from the rotating magnet(s) to fully energize the coil. Do not enlarge the hole in the coil! How magneto coils produce a spark. NOTE: The NOVA II, Mega-Fire or OEM Kohler Solid State Modules (below Ê) can be substituted for the points and condenser for a hotter and more stable spark, and virtually trouble- and maintenance-free magneto ignition system.

NOVA 2, Mega-Fire and OEM Kohler Electronic Transistorized Solid State Ignition Modules -
  • There is absolutely no difference how these modules work. They all work the same. Kind of like the difference between the Chevy, Dodge and Ford vehicles. These are universal and high performance. They improve engine performance by stabilizing the spark, much like crank trigger ignition does. The NOVA 2 and Mega-Fire modules have a durable die-cast aluminum housing. They all produce a hot spark even at cranking speeds, allows the coil to produce 100% voltage. Weather-proof and very reliable. Ignition timing is automatically set. No kick-back and no timing adjustment required. Works excellent with virtually any magneto ignition coil!
  • Suitable for use with most 2 leg or 3 leg magneto coils and with a flywheel having one or two magnets installed internally or externally, and with coil located underneath or outside of flywheel. Works great regardless of the polarity of the magnets, too. Works on most lawn mowers, chain saws, trimmers, garden tillers, snow throwers, brush cutters, one or two cylinder outboard boat motors, etc., with points and condenser ignition. But will not work with most Stihl trimmers and chain saws. Usually, the coil don't need replacing when substituting the points and condenser with one of these solid state modules. If the engine ran, then the coil is obviously good.
  • Works only with magneto type ignition coils originally connected to contact points and a condenser. They will not work with solid state ignition (CDI) coils, battery ignition coils or with flywheels having a ring of magnets installed internally to which the ignition coil (mounted underneath flywheel also) operates off of, such as the bigger aluminum block Tecumseh engines (8hp and up). (With the module, as each magnet passes the coil, it'll produce a spark. And if the spark don't occur at the precise time with the piston at a certain position in the cylinder, the engine will either "kick back" or will not run.) If the magnets for the charging system won't interfere with the magneto coil(s), then these modules should work well. But if the magneto coil(s) operate off the same magnets for the charging system, then neither module won't work. The modules senses when the magnet passes the coil and that's when it makes the spark. If a bunch of magnets continually pass the coil, then the coil will produce an array of sparks.
  • How the timing is automatically set and how it works: First of all, with points, the point gap determines where the ignition timing is set (on systems with a fixed or non-adjustable ignition coil). Therefore, the spark occurs when the magnet in the flywheel passes the coil laminations the moment the points open. But with no points, the magnet still passes the coil laminations at the same moment, which sends an electrical current through a transistor and circuitry within the NOVA 2 module. This current is sent in the form of a signal to the module; within, a transistor opens the primary circuit in the coil and the spark occurs. All this happens at the speed of electricity. The conventional points and condenser ignition system is less responsive.
  • Each module has two wire connections. One wire connects to the ignition coil and the other wire connects to the ground of the engine with use of a supplied installation screw. Comes with detailed instructions. Click here for installation instructions.
    • NOVA 2 Module. $17.00 each, plus shipping & handling.
    • Mega-Fire Module. $20.00 each, plus shipping & handling.
    • Kohler Module. OEM Kohler part # 25 757 10-S. $48.00 each, plus shipping & handling.
Briggs & Stratton's Magnetron™ Solid State Ignition Module. An alternative to using the NOVA 2 or Mega-Fire modules. Installs next to the external two-armature ignition coil that use points and condenser. Provides a hotter and more stable spark than points ignition. Installation instructions included. Will not work with the older three-armature coil or any other type of coil. If swapping the three-armature coil for a newer two-armature coil, a newer flywheel will need to be used, too. NOTE: If no spark after installing the Magnetron™, the magnets in the flywheel will need to be re-polarized by Briggs & Stratton.
  • OEM Briggs & Stratton part # 394970. $22.00 each, plus shipping & handling.
Heavy Standard-Output/Ordinary (20,000 volts) 12 Volt Canister Oil-Filled Ignition Coils. These coils can be used with one ordinary, standard capacity condenser. Spark plug gap should be set at .035". Can be used on most garden tractors, older farm tractors, pulling tractors and with crank trigger ignition systems. Bracket included. NOTE: These coils have an internal 1.5 ohm resistor to prevent premature burning of ignition points. And most failures of battery ignition coils is caused by overcharging of electrical system due to faulty [automotive] battery or faulty voltage rectifier/regulator. Or the use of carbon core (suppression) spark plug wires and/or a resistor spark plug will also cause a good coil to eventually fail because the secondary windings within the coil overheat and eventually burn up from producing excessive voltage to fire the plug. This is why I recommend the use of metal spark plug wires and copper core spark plugs. I have seen too many good high dollar coils fail because the wrong parts was used. Kohler part # 41 519 21-S.
  • High quality aftermarket. $25.00 each, plus shipping & handling.
  • OEM Kohler coil. $83.50 each, plus shipping & handling.
High-Output/Performance (40,000 volts) 12 Volt Oil-Filled Canister Battery Ignition Coil. Suited for high performance engines. Spark plug gap can be set at .060". Can be used on later model automobiles, most garden tractors, older farm tractors, pulling tractors and with crank trigger ignition systems. High quality. Made by various manufacturers. Bracket not included. NOTE: This coil requires an external ballast resistor to prevent premature burning of ignition points and two ordinary, standard capacity condensers or one high capacity/performance condenser (Accel or Mallory) so coil will produce full voltage. (When using two condensers, connect each condenser to the negative (–) terminal on the coil, or to the wire going to the points, and make sure each condenser is grounded.) And most failures of battery ignition coils is caused by overcharging of electrical system due to faulty [automotive] battery or faulty voltage rectifier/regulator. Or the use of carbon core (suppression) spark plug wires and/or a resistor spark plug will also cause a good coil to eventually fail because the secondary windings within the coil overheat and eventually burn up from producing excessive voltage to fire the plug.

Complete 7mm diameter Spark Plug Wires with boots and terminals for above È coils. NOTE: The OEM Kohler spark plug wires rarely go bad or get weak. The only time they need replacing is when damaged beyond use. Also, the terminals and boots aren't on one end of the aftermarket spark plug wires. The terminal and boot for the spark plug is installed on one end and each wire will need to be safely routed from the plugs to the coil, allow some length for flexibility, and cut off the excess wire. Then install the boot on each wire that fits your coil best, strip off about 1/2" of insulation, bend the wire over, install the terminal on the insulation/wire, then lightly crimp the terminal with pliers. The squeezing pressure of the terminal/insulation in the coil tower insures the wire will stay in the terminal.

FYI: Battery ignition conversion is intended mainly for older engines when the OEM ignition parts are no longer available or are very expensive (cost prohibitive). Also, the most hassle when using battery ignition without a charging system integrated with the engine is the use of a remote battery charger. And eventually a new battery will need to be purchased, because they only last a few years. Click here for wiring diagrams.

Points, condensers and spark plugs for other makes and models of engines are also available. Please call or email me for your needs. More parts may be added later. Please contact me if you're interested in any of the above È parts.

High Torque Gear Starter Motors for Kohler K-series engine models K141 (6¼hp), K161 (7hp) and K181 (8hp) single cylinder cast iron block Kohler engine. 12 volt, 16 tooth gear. Each have 20% more wire windings than the early OEM Kohler starter, giving it 20% more cranking power. Cranks engine about twice as fast than an ordinary starter. FYI - The aftermarket starter motors I sell are the same as OEM Kohler starters. Kohler just place a big markup on theirs because it comes in a Kohler brand box and the starter has the Kohler name stamped on it. Kohler part # 41 098 08-S.
  • New high quality aftermarket starter. Comes with a 100% unconditional one year warranty. $85.00 each, plus shipping & handling.
  • New OEM Kohler starter. Comes with a 90 day warranty against defects in materials or workmanship. $206.75 each, plus shipping & handling.

IMPORTANT! Most quality-made starter motors are designed to last the life of an engine. Therefore, if a good starter burns up prematurely, then this means that it has cranked an engine for too long at one time. All starters, including automotive starters, are actually 6 volt motors operating off of 12 volts. This is what gives them so much torque to crank an engine so fast and with ease. So if a starter motor is spun too long (longer than 2 minutes), the excess voltage will burn up the windings. The longer it's spun, the hotter it will get, which causes the wire windings to get very hot, which causes the insulating/separating varnish coating on the windings to melt. When the coating melts, the windings make contact with each other and become shorted out, and you have a burned up starter on your hands. That's why most owner's and repair manuals say to never crank an engine longer than 2 minutes at a time without allowing adequate time for it to cool before cranking it again. (If an engine won't start within 2 minutes of cranking, then it obviously needs a major tune-up or repair!)

High Torque Upper-Mount (mounting bolts are underneath starter) Gear Starter Motors for Kohler K-series engine models K241 (10hp), K301 (12hp), K321 (14hp), K341 (16hp) and K361 (18hp OHV) engines. 12 volt. Each have 20% more wire windings than the early OEM Kohler starter, giving it 20% more cranking power. Cranks engine about twice as fast than an ordinary starter. In addition to the extra windings, the 10 tooth starter gear gives this starter extra torque so it'll crank the engine with less effort. This starter, along with a full size automotive battery, is capable of cranking a 50.5 cid Kohler pulling engine with ease.

NOTE: All parts listed here are NEW, unless otherwise stated. I do not sell cheap junk! As a matter of fact, many of the OEM Kohler K-series and Magnum engine parts are still made in the U.S. The Kohler Courage engines and parts are made in China. As a matter fact, Kohler owns two factories in China that make the parts. And most aftermarket parts listed in this website are also made by Kohler to Kohler's strict specifications. Kohler just place the part(s) in a generic box and sell them for less money. So when purchasing a genuine OEM Kohler part that comes in a box with the Kohler name on it, you're really just paying more money for the name on the box. The OEM [US] manufacturers are phasing out many parts for flathead engines due to EPA smog emissions. But some parts may still be available in aftermarket.

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.
NOTE: Complete engine rebuild kits are available, but a kit will cost more than if the parts were ordered individually. So please contact me with a list of parts you need, and I'll get back to you with a total including shipping & handling. And if you need a part or parts that's not listed here or for other make and model of engines, please contact me and I'll see if I can get it at a reasonable price. Please contact me if you're interested in any of the above È parts or items.

New and Used OEM Replacement Connecting Rods - | Please contact me if you're interested in any of these parts or services.
IMPORTANT! Upon installation of a connecting rod in a Kohler engine, the oil hole in the cap faces 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 for Kohler K-series K90 (3.6hp), K91 (4hp) engine. NOTE: The .010" undersize rods have a small hole drilled through the beam section indicating that it's .010" undersize. Crank journal must be reground .010" undersize to match this rod. The alternative to using an undersize rod - If a STD size or .010" undersize rod is in good condition, the matching crank journal can be reground so it's perfectly round again and then if the original rod isn't badly scored or burnt, it can be resized to fit to odd-size undersize journal. IMPORTANT: To prevent scoring of the rod when the engine is ran for the first time, apply automotive wheel bearing grease or chassis lube on crank journal before installing rod. This will better protect the parts until crankcase oil reaches them.

  • Bore and notch Kohler 10hp-18hp cast iron block single cylinder and KT21, M20 and MV20 twin cylinder connecting rods for installation of bearing inserts. $25.00 labor each, plus shipping & handling.
    • 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 want me to bore a rod for you, please let me know if you want the bearing insert centered in the bore of the rod (piston flush with top of block) or offset .020" or more (up to .125" at no extra charge) to pop the piston out of the cylinder (see below Ê) to raise the compression and help improve air flow 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 yard work, stock or high rpm pulling competition engines. The rod will need to be bored exactly 1.625" for proper bearing to journal oil clearance.
    • NOTE: Being virtually all Kohler K241/M10 (10hp) 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 me 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 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".

  • OEM Kohler part # 52 016 05-S. $46.50 each, plus shipping & handling.

NOTE: Valve dimensions for the KT-series and Magnum twin cylinder flathead engines are somewhat confusing. Kohler is no help on this matter whatsoever. They give their dealers very limited detailed information on all of their parts. So I have to do a lot of research on Kohler parts myself. Anyway, new Kohler engine models MV16, M18 and MV18 intake valves (part #'s 52 017 07-S, 52 017 08-S) are no longer available. And new Kohler engine models KT17, KT17II, KT19, KT19II, KT21, M20 and MV20 intake valves (part #'s 52 017 01-S, 52 017 02-S, 52 017 03-S) and exhaust valves (part #'s 52 016 01-S, 52 016 02-S, 52 016 03-S) are also no longer available. (The KT19, KT19II, M20 and MV20 intake and exhaust valve dimensions are: 1.375" head diameter x 3.900" overall length.) If your original valves are not severely worn, warped, bent or burnt, the valve face can be reground (to either a 30° or 45° angle) and the valve can be reused. If they're bent, they may be straightened, reground and reused. (The OEM [US] manufacturers are phasing out many parts for flathead engines due to EPA smog emissions. But some parts may still be available in aftermarket.)

è New valves for other makes and models of small engines are also available.

Valve Stem Seal for Kohler engine models CH18-CH1000, CV17-CV1000, ECH630-ECH749, ECV730-ECV980, KT715-KT745, PCH680-PCH740, PCV680-PCV740, ZT710-ZT740. Silicone rubber w/metal clamp. NOTE: In an OHV engine with worn or dry-rotted valve stem seals, when the engine is shut down and allowed to sit for a period of time, oil seeps down past the opening in the seal into the combustion chamber. As a result, as soon as the engine is started, the oil is burned, and no more smoke until the engine is shut down, and the process repeats itself. Also, the seeping oil will cause an excess of carbon deposits to build up under the valve head(s), preventing a full flow of air to enter (or exit) the combustion chamber, causing the engine to lose power at higher rpms. And apply clean motor oil on valve stem before inserting valve through seal to provide lubrication of the stem, guide and seal. OEM Kohler part #'s 25 032 14-S, 66 032 05-S.

NOTE: 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, and we have no 18hp cams available.

Professionally Reground 4,000± RPM Performance Torque Cam for Kohler K-series and Magnum engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp) and K361 (18hp OHV). This cast cam profile has stock lift with increased duration and will pass tech for a stock cam. It will add about 3 more horsepower and 2 ft. lbs. of torque to an average stock engine with more lugging power than the OEM Kohler K361 (18hp OHV) cam. When pulling, this cam best with medium performance valve springs (below Ê), reworked and undercut stock size valves, ports made bigger, and the venturi in the carburetor bored out. All this needs to be done to increase the airflow in and out of the combustion chamber. If there's any restriction in and out of the combustion chamber, this cam will not be able to perform at 100% efficiency, and the engine will not be able to produce as much power as it is capable of. The duration of the lobes on this cam helps the engine produce the most power and torque between 3,600-4,500 rpms. At higher rpms, due to the limited duration, no substantial increase in power or torque will result. Tested and proven design over the competitor's. If engine is built to the max, tractor is geared correctly and traction is adequate, engine shouldn't bog down much with this cam. It'll keep pumping out the ponies right out the gate! This cam sounds just like an OEM stock cam. You can't hear the difference out the exhaust. It's perfect for a competing stock pulling tractor or for heavy yard and garden work. Use with the OEM Kohler 1" base lifters. When reusing lifters, roughen lifter faces with 600 grit sandpaper in an erratic pattern to produce a new wear pattern and so the lifters will rotate slightly with every lift to prevent wear to the cam lobes. Use the recommended break-in oil, too. This cam installs just like the OEM cam. Just thoroughly lubricate the inside with motor oil, align the timing marks on the gear teeth, set the end-play and valve clearances to OEM specs, and it should be good to go!

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 unground 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 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 either side of the base circles of the lobes so they can't be readily seen. 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.

  • Outright: $150.00 each, plus shipping & handling.
  • With core trade-in: $125.00 each, plus shipping & handling. Only the one-piece cam (originally with the automatic compression release) will be accepted as a core. Core must be in good condition, no cracks, never reground or welded on before with gear teeth in good condition, minimal wear on points lobe and preferably the compression release tang intact. When sending a core to me, please include a note with your name, mailing address, phone number and that you want to trade the cam in as a core for the Reground Torque cam. I will then deduct $25.00 from the price of the cam. Please send your core to: A-1 Miller's Performance Enterprises, 1501 W. Old Plank Rd., Columbia, MO 65203-9136 USA.
  • 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.
Hot-Stock and Stock-Altered High Performance Camshaft for Kohler K-series and Magnum engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp) and K361 (18hp OHV) Pulling Engines. This is a much more aggressive camshaft than above È. Lobes are hard surface welded on an OEM cast cam, then professionally precision ground to give it a stock lift (.325"-.330"), but much more duration (290°). This cast cam performs best with high performance valve springs (below Ê), reworked and undercut stock size or oversize valves for more airflow, ports made larger and the venturi in the carburetor bored out. If there's any restriction in and out of the combustion chamber, the cam will not be able to perform at 100% efficiency. Due to the increased duration, with an open header pipe, there is a distinctive bellowing "BOOM, BOOM" exhaust sound upon deceleration and at idling speed with this cam. This cam profile helps the engine produce the most power and torque at wide open throttle operation. If used in a 4,000± rpm engine, no substantial increase in power will result. Can be used with OEM Kohler 1" base lifters. When reusing lifters, roughen lifter faces with 600 grit sandpaper in an erratic pattern to produce a new wear pattern and so the lifters will rotate slightly with every lift to prevent wear to the cam lobes. Use the recommended break-in oil, too. This cam installs just like the OEM cam. Just thoroughly lubricate the inside with motor oil, align the timing marks on the gear teeth, set the end-play and valve clearances to OEM specs, and it should be good to go! NOTE: If methanol fuel is going to be burned in the engine and the ignition timing advanced more than 25° BTDC, the automatic compression release mechanism on this cam will need to be removed and a high torque starter motor will also need to be used. Otherwise, the timing would be so far advanced, the spark will occur when the compression release opens the exhaust valve. This will cause the engine to be hard to start, if it would start at all.
  • Outright: $180.00 each, plus shipping & handling.
  • With core trade-in: $155.00 each, plus shipping & handling. NOTE: Only the one-piece cam (originally with automatic compression release) will be accepted as a core. Older, out-dated steel cams for Kohler flatheads will be accepted, too. Core must be in good condition, no cracks, never reground or welded on before with gear teeth in good condition, minimal wear on points lobe and preferably the compression release tang intact. If core has a worn lobe, but the rest of the cam is in good condition, that would be fine because it will need to be welded up (and then reground) anyway. When sending a core to me, please include a note with your name, mailing address, phone number and that you want to trade the cam in as a core for the Reground Torque cam. I will then deduct $25.00 from the price of the cam. Please send your core to: A-1 Miller's Performance Enterprises, 1501 W. Old Plank Rd., Columbia, MO 65203-9136 USA.
  • 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.
OEM Stock Valve Springs for Kohler K-series and Magnum engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp), K361 (18hp OHV), K482, K532 and K582. Recommended for general yard use. Good for up to 4,000± rpm with cam having stock lift. NOTE: Used OEM valve springs rarely lose their pressure. They can be reused as long as they're not pitted with rust, which makes a weak spot and could cause them to break over time.
  • Short Valve Spring. Approximately 1-9/16" uncompressed height; for use with rotator retainer. OEM Kohler part # 235168-S.

Medium Performance Single Valve Springs for Kohler K-series and Magnum engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp) and K361 (18hp OHV). These are more aggressive than OEM stock springs. For competition pulling only; not recommended for general yard or garden use. Designed for the OEM stock cam or our reground 4,000± rpm torque cam with stock lift in pulling engines running up to 5,000 rpms for quicker valve closing to prevent valve float. (Newton's third law of motion.) Valve float allows the engine to momentarily lose compression, cause fuel to spray out the carburetor and the engine will make a "hunt, hunt" sound. As a result, the engine will lose power, and as the weight of the sled is coming up on the tractor, the engine may not be able to recover. These springs can be used with stock size valves, OEM stamped steel/non-rotator retainers and keepers/locks. Do not use with OEM valve rotators! Rotators are thicker, and being these performance springs are much longer (and slightly stiffer) than stock springs that require rotators, coil bind may result at full valve lift, which could break the cam. Can be easily compressed with a standard small engine valve spring compressor. Dimensions: .953" i.d.; .697" o.d.; 2" uncompressed height. Specifications: Seat load: 27 lbs. @ 1.650"; Open load: 70 lbs. @ 1.200"; Coil bind: .920"; Spring rate (lbs/inch): 96. Made by Comp Cams.

  • New. $10.00 per set of two, plus shipping & handling.

Designed for cams with up to .400" lift in Hot-Stock or Stock-Altered competition pulling engines that run at wide open throttle for quicker valve closing to prevent valve float. (Newton's third law of motion.) Valve float allows the engine to momentarily lose compression, cause fuel to spray out the carburetor and the engine will make a "hunt, hunt" sound. As a result, the engine will lose power, and as the weight of the sled is coming up on the tractor, the engine may not be able to recover. These springs can be used with stock size or oversize valves, OEM stamped steel/non-rotator retainers and keepers/locks. Do not use with OEM valve rotators! Rotators are thicker, and being these performance springs are much longer (and much stiffer) than stock springs that require rotators, coil bind may result at full valve lift, which could break the cam. Can be easily compressed with a standard small engine valve spring compressor. Dimensions: .953" i.d.; .697" o.d.; 2" uncompressed height. Specifications: Seat load: 55 @ 1.500"; Open load: 127 @ 1.000"; Coil bind: .950"; Spring rate (lbs/inch): 144. Made by Comp Cams.

New Bronze Governor Shaft Bushings with or without Neoprene Rubber Oil Seal installed in machined counterbore to keep dust and dirt out (which wears the bushing) and prevent film of oily mess on side of engine. (Vacuum within crankcase due to upward stroke of piston draws in dust and dirt, which attach to the oil in bushing, and pressure from the downward stroke of piston blows out a fine mist of oil, in overtime, builds up on outside of engine.) Seal fits snug in bushing and on shaft, and has no effect with operation of governor whatsoever. For Kohler engine models listed below Ê with bushing # 230476-S, 41 158 02-S or 235476-S. NOTE: When ordering, please specify part number of bushing or engine model and specification numbers. And before installing, lubricate shaft with clean motor oil for smooth governor action and less wear to shaft, seal and/or bushing. An innovative concept by Brian Miller, because nobody else advertise this product or offer this service.

Reconditioned OEM Kohler Crankshafts, Balance Gears and New Main Bearings - | Please contact me if you're interested in any of these parts or services.
Reconditioned OEM Kohler Crankshafts - [When available.]

Available for Kohler engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp) or K361 (18hp OHV). These cast iron cranks are genuine Kohler, used and in excellent condition. They have either a 1" or 1-1/8" diameter x 3-1/2" long keyed PTO shaft. They have good gear teeth and may have a worn or unworn connecting rod journal in either STD size or undersize. Which can be reground to .010", .020" or .030" undersize. Although .030" is rare, it's still very safe to use. FYI - To be honest, these are old, used crankshafts. So if you need one with an unworn STD size rod journal, you'll probably have a better chance of winning the lottery than finding a used Kohler K-series or Magnum single cylinder crankshaft with an unworn STD size journal. And if you're going to use a pulley, clutch, etc., on the PTO end, then I will need to know the exact dimensions of the PTO end on your crankshaft so I can match it to one that I may have in stock. For accuracy, measure the length from the oil seal shoulder out. If you have the engine's original model and specification numbers, go to kohlerplus.com (requires Internet Explorer), to find the correct part number for the crankshaft, and then find the dimensions and specifications of the crankshaft is here: CRANKSHAFT REFERENCE MANUAL.

8 Ball Main Crankshaft Radial Bearings for Kohler K-series and Magnum cast iron block engine models K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp), K341/M16 (16hp) and K361 (18hp OHV). Heat treated. These are specifically designed to provide maximum performance through precise ball implement selection. Aftermarket bearing packed with fresh grease from the factory. Good for general yard and garden or high performance use. At high rpms or at wide open throttle, bigger balls run cooler which create less rolling resistance than a bearing with smaller balls. Dimensions: 1.57" i.d. x 3.54" o.d. x .90" width. See note below. Ê NOTE: If yours have more than .005" of play (wear), then it needs to be replaced. Kohler part # 235376-S.

  • New OEM Kohler part. $116.55 each, plus shipping & handling.

NOTE: With the main bearings removed from an engine, and if all the oil is cleaned from the bearings, allowed to thoroughly dry, and then the bearings are spun by hand, and if the bearings isn't worn much or at all, they might feel "rough" and make a rattling sound. This rattling sound isn't necessarily because the bearing is worn. The noise is caused by the balls running dry on the races because there's no oil to separate them. They're simply making metal to metal contact. Try applying a small amount of motor oil to the balls/races and then spin them. They should now be a lot quieter. The same thing will happen with new radial ball bearings. By the way - Most main bearings in a Kohler engine will wear extremely little, if any at all, and usually don't require replacing. Although some main bearings will wear (which is obvious), and need to be replaced. And excessively worn main bearings will make a rumbling noise and the engine will have a more than-usual-vibration.

Complete Exhaust Header Pipe Kits - Top of page | Please contact me if you're interested in any of these parts or services.
If two 5/16" bolt holes needs to be made in the exhaust port for installing the header pipe flange, this should be performed by an experienced machinist with the engine block bolted to a fabricated angled fixture securely fastened on the table of a large milling machine to drill the holes precisely in the exact locations. The holes are to be drilled with a 17/64" or letter "F" drill bit, at about 1-1/4" depth. Then the threads can be cut perpendicular to the exhaust flange with a (preferably new) 5/16-18 NC tapered tap. Use thread cutting oil and go slow when cutting threads in cast iron to prevent breaking the tap off in the block. Because if it breaks off, it'll be extremely hard to remove! (It'll be the beginning of a nightmare!)

A-1 Miller's Repair Service: Professionally drill and tap two 5/16"-18 NC holes in the exhaust port for your block to install exhaust header pipe below Ê. $40.00 labor, plus return shipping & handling.

Exhaust Header Pipe Kit for Kohler K241/M10, (10hp), K301/M12 (12hp) or K321/M14 (14hp) Stock, Hot-Stock, Stock-Altered or 30 c.i. engines with stock size or oversize valves and with or without a working governor.

Kit includes one 1-3/16" i.d. x 1-5/16" o.d. pipe; measures approximately 7" from the block and approximately 19" tall; has a 90°, 4" radius mandrel bend; mounting flange; two stainless steel Allen head (5/16-18 NC) mounting bolts and an anti-vibration brace. Galvanized-coated steel. Very shiny, resists rust and won't discolor from extreme exhaust heat. Designed for use on Cub Cadets and some other makes and models of garden tractors with a 10, 12 or 14hp Kohler K-series or Magnum engine. This pipe has a flange that securely fastens to the engine block with two furnished 5/16" diameter coarse thread Allen head bolts. If your block don't have the two threaded mounting holes, then they will need to be drilled and tapped to accept the flange. There is no other way to fasten this pipe to the block. No gasket is required. Use Clear RTV Silicone Adhesive Sealant instead because exhaust heat has no effect on it, it allows the two metals to have full contact so the bolts won't loosen. Plus, it makes for a professional-looking job because the silicone can't be seen. The flange is also small enough to clear the governor lever. Shipping weight is 4 lbs.

Crankshaft Repairs -
  • Remove burnt aluminum and polish journal to shiny finish. $10.00 each journal. I chuck the crankshaft in my big metal lathe, turn it on slow and use my crankshaft polisher with a sanding belt to remove the burnt aluminum. This works great until the aluminum is gone, but sometimes the journal is scored or worn. Then it requires regrinding to the next undersize. If it's not scored or worn, then it can be reused as is. But if it is worn, an undersize rod and possibly one with a bearing insert is required. If it does need regrinding, then there's no charge for cleaning it.
  • Regrind journal (crank pin) to next undersize. $60.00 per journal. Note: Kohler crankshafts can be reground to .030" undersize and still be safe to use with matching undersized bearing inserts installed in the connecting rod. And all crankshafts, rather if they're automotive or small engine, are checked for straightness before grinding. If they're bent or twisted, sometimes they can be straightened. We also do offset crankshaft grinding to increase the length of the stroke at no extra charge.
    • Once installed and in operation, there is no warranty or guarantee of any kind on crankshaft regrinds.
  • For most makes and models of 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, and then the connecting rod can be resized so it'll fit the smaller undersize journal. 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. The cost for having this done is $100.00 labor for a single cylinder engine, and $200.00 for a two cylinder engine, plus return shipping & handling. If you're interested, we will need your crankshaft and connecting rod(s). An innovative concept by Brian Miller, because nobody else advertise this service .

  • Bore and notch Kohler 10hp-18hp cast iron block single cylinder and KT21, M20 and MV20 twin cylinder connecting rods for installation of bearing inserts. $25.00 labor each, plus shipping & handling.
    • NOTE: If a crank journal is worn beyond specs or badly scored/burnt,it will need to be reground to match the appropriate size bearing inserts. And if you want me to bore a rod for you, please let me know if you want the bearing insert centered in the bore of the rod (piston flush with top of block) or offset .020" or more (up to .125" at no extra charge) to pop the piston out of the cylinder (see below Ê) to raise the compression and help improve air flow 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 yard work, stock or high rpm pulling competition engines. The rod will need to be bored exactly 1.625" for proper bearing to journal oil clearance.
    • NOTE: Being virtually all Kohler K241/M10 (10hp) 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 bearing inserts, I use a metal "plug" alignment tool that I made in my metal lathe 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 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/reamer 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 me 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 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".

The Major Differences Between the K241/M10 (10hp), K301/M12 (12hp), K321/M14 (14hp) and K341/M16 (16hp) Kohler Engine and Blocks -

  • The K241/M10 blocks have a STD cylinder bore of 3.250" and the stroke is 2.875". All of these blocks have an exhaust valve diameter of 1.125" and the intake is 1.375". Some rare K241 blocks have "K301" embossed on the PTO end. These have a thicker cylinder wall than ordinary K241 blocks.
  • The K301/M12 blocks have a STD cylinder bore of 3.375" and the stroke is 3.250". There are no other major differences between these two blocks. These blocks have the same size valves, and most external parts will interchange. Due to the smaller cubic inch displacement, which lessens the amount of air that enters the engine, theses engines use a Carter/Kohler #26, or Walbro #52 (1.07" throttle bore) carburetor.
  • The K321/M14 blocks have a STD cylinder bore of 3.500' and the stroke is 3.250". There are no other major differences between the K241/M10, K301/M12 or K321/M14 engines. The early K321 blocks have an exhaust valve diameter of 1.125", and the valves in the later K321 blocks are the same diameter, which is 1.375". Some internal, but most external parts on the K241/M10, K301/M12 and K321/M14 engines will interchange, with the exception of the early style K241 cylinder head and size of the carburetor. Due to the larger cubic inch displacement, which increases the amount of air that enters the engine, the K321/M14 engines use either a larger Carter/Kohler #28 or #30, or Walbro #60 (1.17" or 1.2" throttle bore) carburetor.
  • The K341/M16 blocks have a STD cylinder bore of 3.750" and the stroke is 3.250". There are no other major differences between the K241/M10, K301/M12 or K321/M14 and K341/M16 engines, except the valves are the same diameter, 1.375" and the K341/M16 blocks have 10 cylinder head bolts. Due to the larger cubic inch displacement, which increases the amount of air that enters the engine, the K341/M16 engines also use a #30 (1.2" throttle bore) carburetor. And most external parts, except the cylinder head and air shields, will interchange with the K241/M10, K301/M12 or K321/M14 and K341/M16 engines.

Kohler engine blocks are not like the small block Chevy V8, they're not all the same. There are many other variations between the Kohler K241/M10, K301/M12, K321/M14 and K341/M16 blocks. If replacing an engine, the best thing to do is have the original engine rebuilt, then all the accessories will attach to the engine with no problems. But if the block is not rebuildable and damaged beyond repair, another block of the same type will need to be acquired. If interested in purchasing a bare block, please email me several detailed, sharp pictures of your block at various angles so I match it to one I may have in stock.
  • Some blocks have wide base flanges (for the wide, deep oil pan) and some have a narrow base with no flanges (for a Cub Cadet or John Deere oil pan).
  • The very early K241 blocks have no indentation for installing an upper mount gear starter. Also, some of these older blocks with flanges have no holes drilled for converting to a narrow base oil pan. (But the holes can be drilled and tapped.)
  • Some blocks have the oil dipstick tube hole next to the cylinder, above the crankcase, while others have no hole present. The hole is either drilled or threaded. Some blocks have provisions for a starter-side oil dipstick tube, and some don't.
  • Some blocks come with balance gears and some didn't. Some have an expansion plug where balance gear stub shafts can be installed, and some have no holes drilled for the stub shafts.
  • Some blocks have two threaded holes for installing an exhaust pipe flange, and some don't.
  • Some blocks have provisions to install a mechanical fuel pump, and some don't.
  • The threaded holes on the PTO end of the block can have different bolt patterns.
  • Some K241 blocks with K301 embossed on the PTO end have a thicker cylinder wall, and some K241 blocks without the K301 embossing have an ordinary thickness cylinder wall.
  • The 12 fin K341 blocks have an ordinary thickness cylinder wall, and the 13 fin K341 blocks have a thicker cylinder wall.
  • Other than all of the above È, everything else on the Kohler K-series engine blocks are pretty much the same.

Engine Rebuilding Service -

I rebuild engines from ordinary stock up to 4,000± rpm governored pulling engines. I can rebuild your engine however you want. Just tell me know how you're going to use your tractor or equipment and I'll build your engine to suit your needs. If you wish to have me rebuild or build-up your engine, I'll need a list of what you want done to your engine or a copy of your club's pulling rules regarding the engine requirements before I can give you an estimate on the cost. I'll build your engine to the limit according to the rules, not less than what the rules allow. I also rebuild ordinary lawn and garden equipment engines too, such as cast iron and cast aluminum block single- and twin-cylinder flathead, OHV and v-twin Briggs and Stratton, Kohler, Tecumseh and 2-cycle LawnBoy. I've never encountered an engine I couldn't repair!

Whenever I rebuild or build-up an engine, and if you wish 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!

Below Ê are details and prices to rebuild your engine - 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, order parts from my suppliers, process orders, package parts and then mail customer's parts at my local Post Office, etc., it may take me several months to rebuild an engine. I also have to depend on other local machine shops to balance engine parts and perform various machine work that I can't do myself. All this takes time. So please keep this in mind if you decide to have me rebuild/build 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

Competition Pulling Engine Refreshing Service Ê A typical pulling engine will last an average of 25 pulls or 3 years of use. After that, it may start to lose power when under load and puff smoke out the crankcase breather vent and/or out the exhaust. When this happens, it's time for a refreshing job. This service is for competition pulling engines that have been previously built, and needs the basic parts to revive the power. It is not a complete rebuild.

Break-In Oils and Procedure for Rebuilt Ordinary (Lawn & Garden) Engines -

For proper break-in of a new or freshly rebuilt engine, use conventional (petroleum-based) SAE 30 weight motor oil containing an anti-wear additive, such as ZDDP (Zinc dithiophosphate), so the internal moving parts, especially flat tappet lifters and camshaft lobes, will get hot, create a wear pattern and produce a hardened surface. Run an engine with aluminum cylinder wall(s) normally (up to 3,600 rpm) for 2 hours, or for an engine with cast iron cylinder wall(s), run it normally (up to 3,600 rpm) for 5 hours. Do not allow the engine to idle at a slow speed for a long period of time! It needs to run at a fast idle up to full governored speed so the crankcase oil can splash up on the critical moving parts. Then drain the oil while it's hot, and either continue to use conventional (petroleum-based) SAE 30 oil, or switch to a quality 10W40 synthetic blend or full synthetic oil for warm weather use. Or use conventional (petroleum-based) 10W40 oil, or 10W40 synthetic blend or full synthetic 10W30 oil during cold winter use. Use no oil additives. Change the oil every 25 hours of engine run time or once a year. Full synthetic oil don't get as hot as conventional (petroleum-based) oil does. It's more slippery and remains cooler than conventional (petroleum-based) oil even after the engine has been in operation for several hours to better protect internal parts for longer engine life.

Break-In Oils and Procedure for Fresh-Built Pulling Engines -

For proper break-in of a freshly built or rebuilt pulling engine, use conventional (petroleum-based) SAE 30 weight motor oil containing an anti-wear additive, such as ZDDP (Zinc dithiophosphate), which places a protective coating between all internal moving parts, will get hot, create a wear pattern and produce a hardened surface, especially flat tappet lifters and camshaft lobes. Run the engine normally (up to 4,000± rpm) for 4-5 pulls. Do not allow the engine to idle at a slow speed for a long period of time! It needs to run at a fast idle or higher rpms so the crankcase oil can splash up on the critical moving pa/U> Then drain the oil while it's hot, and either continue to use ordinary SAE 30 oil, or switch to a quality 20W50 synthetic blend or full synthetic oil. Use no oil additives. Change the oil every 25 pulls or once a year. Synthetic-blend oils get about half as hot as conventional oils. But full synthetic oils don't get near as hot as conventional oils do. It's more slippery and remains cooler even after the engine have been in operation for several hours to better protect internal parts for longer engine life.

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 yard and garden use or for competition pulling, needs to fully break-in for it to produce full power. Rings don't "seat," they break-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 (30°/31° or 45°/46°, respectively), the valve faces needs to wear into the seats to seal in the compression 100%. Wear-in will produce a 30½° or 45½° 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 me 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.

NOTES:

IMPORTANT! If you bring an engine to me in person, sit it in an automotive tire to keep it from moving around during transportation. And please let me know first so I can expect your arrival. But if you decide to ship your engine to me, I don't need everything on it. Just the parts that can wear & need rebuilding or reconditioning, such as the gear starter, cylinder head(s), crankcase breather assembly, fuel pump & carburetor. I need the oil pan on it too, to prevent any dust and dirt from entering the crankcase after the rebuild. Please remove the sheet metal and PTO clutch/pulley, too. I'll need the flywheel on the engine so I can set the ignition timing. Please send or bring your engine when you're ready to the address below Ê. If shipping it, the average crated cast iron block Kohler engine weighs just under 150 lbs. Use this web site to calculate the shipping cost for your engine: http://www.shipgooder.com/. Use FedEx Ground for dependability. Do not use a cardboard box alone! Crate it well and any other parts with it securely so they won't get damaged or lost in shipping. To construct the wooden crate, use 2x2's or 2x4's for the frame work with a skid pallet on the bottom (so a forklift can pick it up without damage) and 1/4" plywood or paneling as covering. Fasten the engine oil pan mounting bolt holes to two sturdy 2x4's on the base of the crate securely with 3/8" diameter bolts. Use extra bracing on the sides and/or across the top of the engine if needed to stabilize it in the crate. Use screws to fasten everything. And be sure to include a note in a sealed plastic bag with your name, complete and correct postal address, phone number, email address (in case I have any questions) and a detailed description of what you want done, how the engine will be used & any other parts you may need. When the work is completed, I'll contact you with the total including return shipping and handling. For payment, I accept cash (in person), USPS Postal Money Orders, cashier's checks, MasterCard, VISA, Discover, American Express and Western Union Money Transfer. (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 me 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 your engine to me, first off, do not use the US Mail Service, UPS or FedEx Express! We and our customers have had too many problems with them in the past. Their "gorillas" have a tendency to damage heavy items, and their insurance won't pay off. They are very hard on heavy packages when they handle them. The packages are placed on conveyor-belt systems and they seem to always drop the heavy ones off of the elevated conveyors, which usually destroys whatever is inside them.

We're authorized FedEx Ground (for anything up to 150 lbs.) and FedEx Freight (for anything over 150 lbs.) shippers because they've been proven to be the lowest cost, most gentle and reliable shipping companies. Here's a great web site that calculates freight charges. Go here: http://www.shipgooder.com/ and type in your zip code, our zip code (65203-9136) and the crated weight of a typical complete 10-16hp Kohler engine (145 lb.). Shipgooder doesn't ship anything. It's web site just lets you see the latest cost of various shipping companies. Contact your local FedEx Ground for more details and to schedule a pickup. Or you can use a major trucking company with a good reputation for shipping heavy, fragile objects. Look in the Yellow Pages and ask around. The reason we say this is because we once returned a rebuilt engine that was crated very well to a customer or an experienced small engine mechanic/technician using a well-known shipping company, and it was almost destroyed in shipping when he received it. You'll have better success with shippers such as FedEx Ground, FedEx Freight, Roadway, etc. Freight company employees are trained in handling heavy packages plus they use tow motors to move the freight around, not like UPS or FedEx Express with their uncaring "gorillas" unloading and loading the trucks. The approximate shipping weight of a crated 7 and 8hp Kohler engine is 100 lbs. And 10-16hp single cylinder cast iron Kohler engine is 145 lbs.

To ship an engine, freight companies require it to be in an enclosed wooden or sturdy plastic crate. It's best to securely fasten it with the oil pan bolts on a pallet made of 2 x 4's and fasten the boards together with long drywall screws, not nails. Then place a 2 x 2 wooden frame around the pallet and fasten 1/4" plywood with a 2 x 2 frame work. Run cross-braces which encompasses the top portion of the cylinder of the block. This will support or stabilize the top of the block and keep the engine from getting ripped off the base. Put a lid on the top and then load it in the trucking company's truck when it arrives with a tow motor. You shouldn't have any problems shipping an engine this way.

To ship a transaxle, this is easier. They don't require an enclosed crate. Just place the transaxle on the center of a wooden pallet 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.

IMPORTANT! When bringing or sending your engine, transaxle or any other part(s) to us, please include a note with your name, address, phone number and a description of what you want done.

NOTE: During the first part of the year, certain parts are back-ordered through some of our parts suppliers because a lot of other businesses are placing their orders for early Spring stock, too.
A-1 Miller's Performance Enterprises is an Authorized Dealer for the Super Tough TRUE GEAR Pulling Gears and Hardened Top Shaft!

NOTE: True Gear stocks a lot of gears, but late Winter through early Spring is the rush time when they fill most dealers' orders. Customers' orders may be delayed due to this fact. | Please contact me if you're interested in any of these parts.

True Gear Custom Two Upper Cluster Slider Gears and Two Lower Stationary Gears for IH/MTD Cub Cadet transaxles. NOTE: Tooth count on upper cluster gear and matching bottom gear must add up to 52. Listed are the most popular sets.

1st and reverse gears (The 1st and reverse gears can have all the tooth counts for what ratio you would like; 13t over 14 teeth up to 29 teeth), 14/15, 14/16, 15/16, 15/17 , 16/17, 16/18, 17/18, 17/19, 18/19, 18/20, 19/20, 19/21, 20/21, 20/22, 21/22, 21/23, 22/23, 22/24, 23/24, 23/25, 24/25, 24/26, 25/26, 25/27, 26/27. Other gear sets are also available; from 13 teeth to 28 teeth in any combination you would like. Sets includes upper and lower gears. Exception: for the upper 13 tooth cluster gear, reuse the OEM Cub Cadet 39 tooth lower gear.

  • Above È gears, any combination. $120.00 per set, plus shipping & handling.

Custom Gears Installation Information: On the custom 2nd and 3rd gear set, the bottom gears are wider than the Cub Cadet OEM bottom gears. Therefore, the cone-shaped spacer at the front of the lower pinion shaft will need to be narrowed about .050" so the pinion gear will mesh correctly with the ring gear. Exception: for the 13 tooth cluster gear, reuse the OEM Cub Cadet 39 tooth bottom gear. And if the upper gears are larger in diameter than the OEM gears, the shifter fork may need grinding for clearance. Or if the gears are really big, a billet shifter fork will need to be installed. Otherwise, 1st and reverse gears and everything else should remain the same in the transaxle.

Install custom upper and lower transmission gears in your IH Cub Cadet transaxle, or complete IH Cub Cadet transaxle repairs, gear changes and modifications.

  • (Cub Cadet dealer: $96.00± retail each!) FYI - I'm not an OEM Cub Cadet parts dealer. Cub Cadet won't let me become a dealer because there's already one in my area. (It's another way how big businesses support other big businesses, or how the rich help the rich get richer.) Besides, competition from different dealers in the same area help keep prices low. I think this is unfair business practice because by allowing only one dealer in a wide-spread area can have them gouge (overcharge) unsuspecting customers on parts and/or repair costs. They probably laugh all the way to the bank after every sale, too.
