Folks, I'm looking at buying a 1972 Johnson 6 HP.

I swear I've searched this forum and online, but I cannot for the life of me find somewhere that has the specs for compression.

Can someone please tell me what the specs should be and if possible pls give an online source as I've had to ask this question before about another motor.

Thanks.

Nor will you find one, they really didn't publish a "spec" sheet for compression numbers. I'd expect 80+ and close on both cylinders to be good, great would be 100+, 50 and lower may have some issues.
