High Pitch Squeal
I have a high pitch squeal on occassion. It sounds like it is coming from the clutch side of the engine compartment. It doesn't do it a lot but some times it does it. I am thinking maybe the seal behind the primary clutch on the engine. Or I am thinking it is just the belt rubbing on the primary clutch. It comes and goes, but the sled runs great. I mean this thing just pulls out of the hole and runs hard. It is a beast.
Oh and the plugs look good so I don't think it is running lean from a bad engine seal.
Another thing is sometimes I am getting a bad chatter/vibration. I checked the chain and it seemed loose and I was able to turn the tension bolt for the chain in quite a ways in. If I need to swap the chain out I can because I have another set of sprokets and chain.
