[30 A Ripper]

Gave all my stuff to my son a few years ago but will go get it this weekend.

But heard someplace that my old Sears compression gage won't work as block plug hole diameter is too large & the scale too high.

Maybe I could make some sort of rubber sleeve to slide over mine.

Don't think I'm real concerned on exact accuracy but would like to see how cylinders compare. Probably a good thing to check before I replace that leaking exhaust manifold gasket....
