Forgive the rookie questions, but........
This is the piston in the 361 i got off ebay. Sorry for the crappy pic, but i guess i need to uptate my old beater digital camera that the macro doesn't seem to work worth a flip. Anyway, there are a couple of real light lines on the piston above the rings. Rings look good as does the piston below the rings & from what i can see of the cylinder it looks good.
Also, i have never done a compression check on a saw before. I got the Lisle recommended here in another thread. What is the proper procedure? The first time i checked it i pulled tentatively & got 100psi. Then i pulled with authority several times until it maxed at 150...am i doing this right?
So, with a 150 compression, do i worry about the faint lines, or should i hone & re-ring?
Also, the bar cover has some corrosion all the way through, if anyone has one they are getting rid of, pm me.
