Update: Ran a tank through this saw about two weeks ago 165psi. Ran another tank and a half through it and it is now at 190psi. I used a self cut gasket from 'gasket paper' and am running a B class piston in the A class cylinder
, squish is a shade under .020. I am going to keep a close eye on it and will proabably put a thicker gasket in. Saw is running fat, four stroking bar buried, has a choked up muffler and is running a 64DL Prolite. Lots of noise from the clutch, put a new clutch spring in but it did not help. I noticed today when I was checking it for damage after running it, there was none, one of the clutch ends is a little thicker and the new Oregon drum I put on the saw when I switched over to the worm gear oiler setup is a little out of round so it klings and klangs quite a bit. It is definately thirsty, very thirsty.
