LOL I only have 3 saws, a 30cc Echo, a 50cc Dolmar and a 79cc Dolmar, all built before the EPA stuck their sticky fingers in the pie. I have been toying with the idea of sending all 3 out to Mastermind to get ported.

The Echo has a 14" & 16" bar, the small Dolmar has a 20" bar, the 7900 has a 24" and a 32" reduced weight bar. 95% of the wood here is Oak or Maple. Sandy soils, so I run a semi-chisel and all of my chains have been cryo treated. I've noticed that they last longer.

With the sandy soils, if I'm cutting near dark I still see a spark once in a while even though I am cutting part of the tree that was 50' or so in the air. Dang squirrels with sand stuck to their feet are the problem I think.
