I got this 81 about a month ago. When I got it home the crankcase was full of gas. The previous owner had tried to get it running in preparation for selling it. I am concerned that in the process he may have scored the cylinders a bit. On the left side I get 78 psi dry. On the right I get about 85 dry. Put a shot of oil in each spark plug hole and cranked it over a couple times. Now both sides have about 110 psi which would indicate ring bypass. My question is what is normal compression on a used engine of this type?
