Ok guys I know its not a buggy, my son has a "china knock off" Hensim ATV that has the GY6 150cc motor. Bought it new over a year ago and it has ran great until recently. We started to get a "miss", "sputter" whatever you want to call it about a month ago. At first I thought it was bad gas so I added some STP fuel treatment and it seemed to take care of the problem. Now its back! I am thinking now that the spark plug may be fouling because it seems to happen most when the engine is under a load. So that being said does anyone have any insight as to what the problem may be. Also since it is the GY6 150cc, will the performance parts for our buggies work on this ATV. Thanks in advance.
