Can anyone tell me what the compression values should be on a 1972 Johnson 65 hp
Thanks racerone. The motor hasn't been cranked in about 4 years. Just thought I would tinker with it a little to see if it would crank. I checked the compression and it read 70- 80 psi on all cylinders. Is this bad low and what would this mean by having low compression?
