bootser..........Ford specs fer 8N flathead engine is 90psi min. New engine is about 125psi. Most good engines run about 110psi. With low pressure you are quoting, ALWAYS run a dry (5-rumpas min) and then a WET. Squirt about 1-oz oil down the sparkie holes and then re-take yer compression readings. Good engines will up the wet compression about +10psi. Really BAD engines will up the compression +30psi. Many times low compression is "stuck" rings. Gitta can of MMO or ATF and squirt some down the sparkie holes ...then... wait a day. Do a dry compression test again. Remember, write all them compression numbers down (we all have CRS) Then iff'n you don't understand what yer compression numbers mean, post'um. Simple, eh?
BTW, new compression gauges have "instructions" and are NOT expensive. ($25, cheap) ........Dell
