I have a Buddy that his sled will not run good. almost like a mis in the spark or it is loading up. After riding it yesterday, the plus were a little wet. The Bellows are new, Reeds are good, Temp Sensor New, Spark seems to be ok. Carbs gone thru serveral times, when it idels, simetimes it will shut off. New Voltage Reg. Awsome Compression, Should he be looking at carbs or Electric? Anybody know how to test the stater? (OHM's Etc). It si almost like it is missing. The Needl is on the 3rd pos from the top of needle. He said that is always been that way. Can not find any broken, cut, etc. wiring. Help. Thanks
