I got this saw about a year ago. Dirty but not used heavy, looks like a firewood saw rather than a tree guy or production use. Compression feels great. Some slight scoring on ex side. Looks worse in the picture, I couldn’t feel it. Compression is 180psi. Cold no oil. Interesting it came with a new plug. Seems to have been put aside for no spark. I’m going to pull the jug to get a better look. The piston has the machine marks still, I cleaned one up on a Dolmar and it remains clean after plenty of use. The cylinder remains to be seen.
