What makes the plugs foul so much, i know its gettin to much fuel But could to much oil?? Only my right side will foul a plug. Left side never does...this is same machine that bogs on low end, but runs killer from mid to high end..Adjusted carbs and are snyched. But seem to foul out right side plug somewhat often...Gonna check e clip and see if they are the same, Does one cylinder need more fuel then other...Thought i read that somewhere...Just wonderin if carbs are on wrong cylinders.?
