I think I originally posted this on an old thread....Can one of you help me??? About a month ago my son's Desert cat 90 just started losing power. He has ridden it three times since then and today it will not go unless you get off and walk next to it.Engine seems to run fine but the transmission just doesn't want to go unless there is NO weight on it...

 

is the desert cat a 2 or 4 stroke engine?

 

Sorry I forgot to mention it is a two stroke.

 

sometimes the carburator needs to adjusted,and can cause this type running, also it might be on the verge of having a piston seizure that would also act like what you're discribing, i would try adjusting the carb first and checking for air leaks around the cylinder base gasket.

 

I really appreciate it. I will try these out today. Thanks again...
