compression looks pretty low overall to me. Either an inaccurate gauge or fairly even wear on the rings.

Unless your motor puts out 60rwhp, I'd think test was done incorrectly. It's well below typical compression numbers.

the reason I suggest rings on #4, if from the oil on the spark plug and the higher compression number.
