Question about 2003 Yamaha YZ 250
1998 yamaha timberwolf 250 atv
all of a sudden won't idle steadily - cleaned carb, fresh gas, new spark plug, new air filter.
rpm fluctuates and engine will cut off if don't constantly fluctuate choke,
any leads greatly appreciated.
Check the rubber boot that joins the carby to the engine to often have seen the hose clamps over tightened therefore creating a split in the rubber letting to much air in giving the rough idle eventually you wont be able to start it at all (have a good thorough look inside an outside of boot doesnt take much)
