My kingquad only has 200 miles on it for a 98. The guy that had it let it sit around most of the time and never drove it in the last 10 years. I drained all the gas out and cleaned the carb 3 times, changed plug. The bike will start instantly whether its hot or cold . Runs ok if you don't hammer the gas, but at high RPM it sputters and after about 15 minutes of riding it really gets rough. Then stalls and wont start for about 20 minutes then it will start and idle real low and stall if the gas is touched. I'm not sure what else could cause this. Bike is mint shape and was only used for cleaning snow.


ignition coil? what else? any ideas?

thanks in advance.

 

valves have clearance but still no go. It will fire and run for 5 seconds on real low idle, then quit. Bike wont even start today. This has me stumped. Any incite would be appreciated.
