Got a Stihl 056 on the bench, first time for one of these. Compression is measured at 130psi on two gauges, one is very sensitive and the other less so, if the bore or piston is a bit worn, the less sensitive one usually reads 20-30psi lower than the other
I am getting 130psi on both gauges on a cold engine that is fueled so the bore isn't dry - is this about right on this type of saw - I know some of the more modern ones run at 150 -175psi.
Anyone got any experience - if this is fine I won't tear down the top end but if the opinion is that it is low, then I will tear it down and take a look!
Cheers from the UK in advance
