old mule power problem 1987

[buckshot0203]

i have an older kawsaki mule 1000 model kaf 450 and i have no power under load and can only get about 10 MPH out of it on flat ground and cant even climb up a hill with it . ive cleaned the carbs out and replaced the fuel lines and filter. anyone got any ideas what might be wrong?

Hey Buckshot,

If you have ruled out everything else that could be limiting the engine speed, and nothing comes up as a problem, go and read a post I just did on carburation problems and my fix. I have found that most of the mysterious running problems are fuel related - that is partially clogged fuel delivery galleries to the jets. This is an extremely common problem that mechanics usually charge large bucks to fix by removing and "boiling out" the carb.

Good luck,

Will
