I did a comp test on this motor recently and got some weird numbers. I don't know what they mean exactly. Top cylinder is 120. I tested the bottom cylinder 7 times and got 5,5,120,5,5,5, and after putting a little oil in, 10 psi. I can't figure out why i would get good comp once only. If the piston ring is wasted, how could i get 120 even once? I imagine i need a new powerhead or an overhaul. But i figured i better ask before i start anything like that. Motor starts up for few seconds and then sputters out. I did have it idling ok in a bucket for awhile until i gave it some throttle and it cut out. But the fuel line was definitely kinked at that point. I'm hoping to use this motor on a little hydroplane. Thanks.
