New to the ETEC's, picked up a 16' with 2400 miles. As far as i could tell it ran like a top! Rode it twice no problem lots of power. Found it has a exhaust leak at the manifold to head due to a missing bolt made appropriate repair and 20 miles into Cooke City lost all compression on the Mag side. Plug looked a little oily but not covered with metal fragments or anything. I have not torn it down yet. Looking for any input or thoughts to start me in the right direction. Thanks
