When you guys talk about compression are you testing with the engine warmed up or cold? I been reading some threads on here saying they are getting 175psi on some saws. I bought a new compression tester and did my 2007 372XP cold and only got 130 psi max. That must be getting on low side? The saw still starts and runs good. I'm just wondering how bad is 130psi from a 8 years old 372xp?
