Bruce,
It's got 128psi compression. I pulled the head this weekend and found the head gasket to be leaking, as well as the exhaust valve not sealing well. Come to find out the owner had tried to start it on ether, and the first start it (in his words) "exploded". Lapped the valves, and will try to get another head gasket today. Don't know if this will fix the old problem, but I feel it should at least let it take throttle again.
