Re: Powerhead compression bench test

Well, it’s too bad you didn’t check compression prior to disassembly, oh well. You can clamp it down somehow and pull it over with the recoil, but don’t squirt oil in the cylinders, this will just hide problems.
You mention this poor thing has been cobbed together with many mcgyver repairs, so it probably isn’t worth doing a lot of powerhead work…
I would just pull the cylinder head to have a better look if compression readings seem low…You probably won’t see more than 70-80PSI, which is normal for these engines.
