Welcome to our web page catalog. We specialize in garden tractor pulling parts and custom items made for the older International Harvester Cub Cadet garden tractors. However, many components work well on other makes of tractors that are powered by Kohler or Onan engines. These include John Deere, Ariens, Bolens, Case, Allis, Ford, Gravely, Jacobsen, and Wheel Horse.
The ignition system components are our specialty. These products have been garden tractor Pull Proven; that is, tested under the demands of competition tractor pulling. They've also been bench tested for thousands of hours to assure reliability in every-day mowing applications. Many satisfied customers attest to improved, consistent performance with vastly increased running time between tune-ups. The PointSaver™ ignition modules are unconditionally guaranteed for one year against failure. Should you be dissatisfied for any reason, simply return the module for exchange or full refund your choice.

Don't rebuild or replace that expensive and unreliable mechanical fuel pump when you can update to this! The Facet Electronic Fuel Pump (sometimes referred to as the "cube" pump) is the most reliable and compact alternative available today. Perfect for any lawn and garden tractor application, this pump offers a 7 GPH flow rate at 1-2 psi delivery pressure, just right for Kohler and Onan carburetors. The tailored output pressure will not override the sensitive float needle seat force, a common problem when using automotive-type electric pumps. Both inlet and outlet ports are tapped for 1/8" pipe thread fittings (not supplied).
The solid state design ensures longer life when compared to other electric and mechanical pumps. It eliminates hot weather vapor lock problems and faster engine starting in cold weather due to virtually instant fuel delivery as soon as the key is switched on...no more extended cranking just to prime the carburetor bowl! Easily installed with instructions supplied. For 12 volt negative ground electrical systems only.
Facet Solid State Electronic Fuel Pump price each - $53.00 plus $9.50 Priority Mail Shipping
Referred to by some as a "cheater cam", this camshaft profile has been popular in quarter-scale, stock class puller engines. It is fully legal due to valve lift being below the tech limit of .330 inches. However, inlet and exhaust duration plus overlap have been extended to allow better top-end performance with little sacrifice in low-end torque. Good idle qualities are still retained. Stock Kohler valve springs and lifters may be used.
These camshafts are reground from stock cores on a dedicated cam grinding machine. Surfaces are then carburized (hardened) for durability. I can personally attest to the quality - I've been running one of these cams in my hot rodded K301 for 9 years (approximately 400 hours), used for typical lawn-and-garden applications. Valve lash never changes and performance is stellar!
This part is sold on an exchange basis only. You must send in a serviceable camshaft core to purchase this part. "Serviceable" is defined as a used Kohler K-series single cylinder camshaft complete with working compression release, no chipped or missing gear teeth, and minimal wear on breaker point cam.
Do not send in the older style, 2-piece ignition advance camshaft in for regrinding. In most cases your core will be reground and returned to you. Please allow 2 - 3 weeks for turnaround.
For use on Kohler K241 (10 hp), Kohler K301 (12 hp), Kohler K321 (14 hp), and Kohler K341 (16 hp) single cylinder engines only.

Finest coil available for the single-cylinder Kohler!
From competition pulling tractors to those used just for mowing, the Bosch Blue sets the standard in ignition reliability and high performance. Epoxy filled for vibration resistance, these coils are quality manufactured by one of the oldest and most reputable automotive electrical names in the business, Robert Bosch. Primary resistance is 3.2 - 3.5 ohms, which is slightly lower than the standard equipment Delco coil. This means the Blue draws more current (for a hotter spark) but can be used as an exact replacement coil using stock condenser and breaker points. No additional ballast resistor required.
Comes complete with plated mounting clamp and removable spade terminals on both primary posts. And it's finished in the classic electric blue paint that lets everyone know you're running the best! For use on all Kohler K-Series single cylinder engines equipped with battery ignition.

Next best thing to a full flow oil filter!
The single cylinder Kohler K-series engines are splash lubricated. As no oil pump is used, there is no easy way to adapt an oil filter. Thus, stray ferrous metal particles remain suspended in the oil until it is changed. These contaminants can damage both plain and rolling element bearings, shortening engine life. A magnetic drain plug will attract these harmful particles and prevent them from circulating, thus protecting bearings and keeping oil cleaner. It's like having a perpetual oil filter - simply wipe off particles during an oil change, then reinstall.
These plugs are fitted with a powerful ceramic disc magnet, offering high strength with large surface area. You'll be amazed at how much metal they collect between oil changes, especially on freshly rebuilt engines.
Size is 3/8 - 18 taper pipe thread, commonly used on many small engines. This plug also fits Kohler AQS (Quietline) engines that use a flanged 3/8 - 18 straight thread plug. You'll find the taper thread eliminates leaks and there's no finicky gasket to replace.
Magnetic Oil Drain Plug for all Kohler K-series Engines price each - $3.00 plus $3.00 Priority Mail Shipping
Have you removed balance gears from your K-series engine and discovered that it now vibrates with newfound gusto? Or have you thought about buying a newer, twin-cylinder tractor just to get rid of the single-cylinder shakes? This modification will greatly reduce transmitted vibration, making your K-series engine run noticeably smoother, restoring both your faith in Kohler and the feeling in your hands and feet.
A 50% RBF (Reciprocating Balance Factor) is a good compromise in reducing transmitted vibrations from a single-cylinder engine. For reasons unknown, Kohler engineers under-balanced these engines (only 29% RBF on the K301) such that they transmit unnecessarily high unresolved reciprocating forces about the vertical axis. Installing the Crankshaft Balance Plate Kit restores a 50% RBF to the engine, making for a much reduced vibration signature. The improvement in crankshaft balance yields lower main bearing loads contributing to longer engine life, reduced transmitted vibrations, and greater operator comfort.
This inexpensive kit requires simple and straight-forward machining of your crankshaft which can be done at a local machine shop in usually less than one hour. Or, if your personal shop is equipped with a mill and drill press, you can easily do it yourself. No further balancing of the crankshaft assembly is required if installed per the instructions. The kit consists of a precision formed, high-quality steel Balance Plate, two grade 8 mounting screws, and detailed instructions. This modification is for Kohler K301, K321, and K341 single-cylinder engines only.
We now offer machining of your crankshaft to accept the Balance Plate. Send us your crankshaft and we will machine and install the Balance Plate for a professionally done job. Price includes Balance Plate. Machine and Install Balance Plate on Customers Crankshaft - $120.00 plus $17.00 Priority Mail Return Shipping

Ever wish you had power steering on your IH Cub? This simple modification will lessen steering effort immensely by reducing friction. The stock steering box uses a grease-lubricated washer that rides against the housing, taking all thrust loads. This kit replaces the friction-causing washer with a ball-thrust bearing, a clever retrofit discovered by Donald Mayes. As these parts are external to the steering box, this is one of the easiest modifications to perform, taking about 1/2 hour to complete.
Kit consists of a NICE 605 ball thrust bearing, precision steel shim washer, and quality Nylock jam nut. Instructions on installation and adjusting are included. For IH Cub Cadets models 70 through 169, 800 through 1650 Quietlines, and all 82 series.
