replaced spark plug, replaced cdi, new exhaust, and new carb. First go around she started up real nice, the exhaust is real loud but provided a lot of power. than after a minute we went bake to the same problem as before. I engage the clutch compression happens, however no exhaust noise and I can hear the the throttle working. So I think its a spark issue. If I'm running super rich will that cause the spark plug to get too wet to work?
