I'd like to know the recommended way to test compression in my MS200T (and in my MS361).
I pulled the plug and screwed in the adaptor and hose for my compression tester and pulled the starter cord a few times. I got up to 120PSI and suspect that I could have read higher pressures but I simply could not pull the cord any harder and felt like the pull cord would break if I tried.
What was I doing wrong or what could I have done differently? With engines having a starter motor, I have done many compression tests over the years (I've worked on cars since about 1962) but this is the first time with an engine having a pull cord to turn it over.
Thanks in advance.
(By the way, the saws both run great. I just felt like doing the measurement.)
