[QUOTE="who pooted?, post: 276845, member: 940"] Update, got ignition spark checker, and flywheel puller. [u]Checked spark[/u] Upper cylinder bright consistent flash, and strong light when revved motor. Lower cylinder weak inconsistent flash, and seemed to be bright at rev, but definitely not as consistent as top cylinder. Coils looked fine, maybe the water in the lower cylinder is causing this? I've got pictures of the ignition system below. Both coils looked clean and no cracks. i did notice one of the points looked somewhat cupped where they touch. Also seemed to be a good amount of grease near crankshaft where the wick is. Found hole in lower unit, so will get that fixed to keep the oil clear. Also please notice grease/oil build up behind starter on the head of the motor. Would new gaskets keep this from happening? [/QUOTE]
