Re: Compression

I get 45# across them all. This from a tired engine last redone in 1961. It doesn't leak or burn oil and has pretty good power [ I'm in no hurry with it]. That said, not all compression gauges are created equal. If all your cylinders are within that 5# range and the engine runs good, I would think you're OK.
