Compression Friday night was 168 across bolth the gravel looks gold I'm concerned it's the valve seat rear cylinder was kinda weak ... It runs great for about 5 min then it bucks misses loses a cylinder and wants to kill itself .... Cleaned the carbs checked plugs got oil on the front plug threads not in the combustion chamber was told it was stator pick up been told I was fuel delivery I just scoped it and found this I'm pretty screwed up because it's my daily... I've got loud noise coming from the right side of the case when it's running loud tapping ect... Like I've said before I'm open to input and direction
