    My 99' Grasshopper has a liquid cooled Kubota gas engine. When I have the throttle on idle, the RPM's go up and down. Its been progressively getting worse. At full throttle every thing sounds normal. Any ideas?

    Have you tried cleaning the carb? Possibly gummed up jets. Weak spark at idle? Just a few ideas off the top of my head. What have you done or checked yet?
