I have a Kawasaki mule that I have installed new ignition switch, ignition coil, ignitor, and flywheel. Spark is still extremely weak. Mule model:KAF300B Any advice is appreciated.

I apologize, I read the previous comment wrong. Found the solution. Fuel pick up had a crack that the naked eye could not see. Replaced pickup and that corrected problem. By the way for future reference this was on a grasshopper 327k

If it’s not Stihl you are making a mistake. Coming from an echo dealer

This is an efi unit ran with the Delphi

Running on one cylinder with identical compression on each would not make me think it would be an internal problem. Did you test spark through coil wire? Possible carb flooded cylinder, engine oil viscosity became thin enough to get past rings and when engine heated it evaporated gas from...

When motor gets in load motor loses power and takes roughly 30 seconds to resume operating rpms. New high pressure fuel pump, pickup fuel pump, plugs, and fuel lines. I have performed a ecu and tps reset followed by a tps learn procedure. Motor runs great with light loads but once in thick grass...

I am b&s mst. New to the sight. I can access all files. Let me know model type and code and I can find out anything you need to know

Carb is dumping excessive fuel under load when accelerator pump is connected. Runs like a top disconnected but leaks fuel when motor is in shallow water mode. No gas in crankcase and carb holds 15psi

Carb rebuild and accelerator pump rebuild are two separate part numbers

Yeah restrictor is in tube from accelerator pump. After bypassing accelerator pump motor runs great with no load but under load motor fails to produce enough power to get the boat to plain out. I also have a new carb coming to see if there is a problem with the rebuild. Will be Wednesday before...

Alright this carburetor has an accelerator pump mounted to the bowl of the carb. Carb and accelerator pump have new rebuild kits in both. If I remove the hoses connecting the accelerator pump to the carb (bypassing the accelerator pump) then the motor runs fine.

Not exactly sure on the type spark tester this is. Kohler part # 25 455 01-s. Let me know if this is not correct and I will try again with the correct spark plug tester.

Is it possible to bypass the accelerator pump mounted on the carburetor on this model?

This style motor has your typical pto switch to activate the propeller. If the pto is not engaged and you increase rpms and have the same outcome would that still be the problem? Thanks

The Spartan mowers are a complete nightmares to work on. Just continue to pray that none come in your shop.

Motor should mount up correctly as long as mounting house line up. The problem we have always ran into is the wiring harness connection. If you can find a schematic wiring diagram for both it will be fairly simple.

Very easy to remove. Use small screw driver to remove cap on back side of each end of damper and it will come right of

I have a kohler motor powering a prodrive boat motor. Customers problem is no power under load. I have cleaned carb and installed new heads, valves, intake gaskets, head gaskets, and spark plugs. Still has not corrected the problem. Used kohler spark testers to test ignition coils and they...
