Well I'm back with my tail between my legs. I got the saw back together, and took it to have a shop tune it. I let it warm up yesterday check the tune with the tach(It was 13,900 rpm). I then started working up the tree. Well after about 5 cuts as soon as I finsih the cut the saw died. This is what happened last time. SO I stopped and pulled the muffler and sure enough the piston is starting to show some scoring on the side of the piston.
So my question is, is it possible to be running lean at 13,900rpm?
