just did that mate even did it twice just to be acurate washed some fuel through in between tests and readins still macth with a small amount of oil like you said my compreshion goes from 116psi to 145psi i will try decarboning the old rings and piston groves then do another test just to make sure they are not sticking and are moveing freely in the groves if not ill have to do rings also "damm" ...
how can you identify if your piston is a genuine oem stihl upon inspection? ...
and do aftermarket piston kits like meteor brand run in stihl oem jugs
