K series compression test with ACR?
the K series Kohlers have an automatic compression relief feature. How does that affect a compression test and what psi value would you like to see? I tried to do one with my 149 project engine (which seems to start and run fine) but I only get about 50 psi on the compression gauge. I went over to my 108 and tried to do a compression test and got zero. That engine was just overhauled, starts and runs great. What gives?
