Calling them when you can't find what you need online frequently gets results.

I bought mine through my local forklift dealer/repair shop. They once repaired Cushman Industrial Vehicles, so knew where to get parts for them, but one of the above sources should be able to help. In previous posts I posted the Keihin Carb Exploded view and Cushman parts list for the carburetor. It might be of some help.

If the bypass filter's pressure regulating valve is stuck, the OEM fuel pump will over pressure the needle valve and float in the carburetor causing gas to exit the float bowl vent and run down the outside of the carburetor. It will also cause the motor to run very rich, if it runs at all. The OEM fuel pump can, and will, over pressure the carburetor if it can't return the excess fuel via the bypass filter to the tank. I have some Keihin Carburetor spare used parts, but I would hesitate to give you a float and needle valve, because what I have is likely no better than what you already have.

I have most of 2 spare OMC 22 hp engines, mostly disassembled, cleaned, and bagged. I do not have any cylinders.

Cylinders and valves seem to be the weak points of these engines, and keeping the engine from overheating will extend their life. To avoid overheating, the air temperature controls that open and close the damper doors in the front of the engine must be kept working properly, or in my case locked in the open position since I could no longer find any of the temperature control bellows assemblies or linkages. They help to get cab heat from the engine and allow the engine to warm up faster in extreme cold conditions, but aren't necessary in temperatures above about 20 deg F for engine performance. but all of the finned areas of the cylinders and engine block must also be kept clean, and the engine must be able to get full air flow around and through it. If not, exhaust valves will break, and/or the cylinder walls will be scored. Another problem is that the spark plug threads in the aluminum cylinders are easily damaged. I always use an anti-seize compound on the spark plug threads and I am very careful not to cross thread the spark plugs when inserting them. Out of the total of 3 engines that I have, only the engine in my Truckster has good cylinders and valves. There are no good cylinders with my 2 spare engines. They still sell new cylinders with valves, but they are expensive.
