Looks like you still have plenty of room for adjustment with the squish if you want to go tighter. I would guess compression around 185-190 psi?? I could trim the cylinder down for you if you would like to mess with it more and still run a gasket. Looks and sounds good Roland, have you modded the muffler? Get it in some bigger wood, lean it out a bit and let her eat!!!
I am quite happy with this saw like it is for the moment, thanks for the offer though. I opened up the muffler a bit (there is an internal baffle that an be bent).
Generally, I tune my saws a bit rish during break in, but will finetune later in some bigger wood. thanks for your input, folks.
