Hello guys, i was so lucky today to get a 262xp in decent shape shipped over to me for only 90 euro's! And thats not all. The saw has no decomp and a HD 87 carb i tought these saws were the better models (correct me if im wrong). So the saw had just about 150psi compression, my question is want a little more but how can i easily measure the squish? And will i be able to start the saw with more compression because i already feel it plopping hard at tdc. Im also thinking of just put a new ring on the piston or a new piston. What are your thoughts about improvements i am not realy a pro in porting and i dont want to ruin this beauty so that is not realy an option.
