We own an automotive repair facility, and I am a certified technician

We do have a fairly new compression gauge kit from Mac tools, and another one from Snap-on tools.

I just thought I needed a small engine compression gauge for these KT100 motors.


But yeah, I think from now on if I want something done right, I’ll do it myself, I just thought there was more science to keep those engines freshened up and legal.

What should be my ring gap, with a feeler gauge at the ends?

Thank you for all your advice
