Hi, We just acquired an old John Deere AMT 600 (Gator precursor). It has a Kawasaki FZ340-AS10 engine. It sat for 4 years prior, but I got all the carb passages cleaned out with cleaner and air. It runs great at high rpm's, but the idle speed is erratic and it barely stays running. I have the low speed screw set so that it stays running although it misfire a lot. Does anyone have adjustment procedures for the governor? I'll try pulling the plug tomorrow, although it is new. Anything else I should check? Thanks.
