What do you run your 440 at (rpm)?
Kevin
that patricular saw cleans up out of 4 stroking about 14.7-8 it's stihl barely 4 stroking at 14.2-14.3 and that is where I run it,,,, in fact That is pretty much where I run all of my work saws,,, just inside of beginning to burble,,,,,, the plugs are usually dark brown and I have never (knock on wood) stuck a piston,,,,,,,
