Saving feedback getting on the chainsaw repair group on the stihl 039 pop up piston he sent out to folks to test.

Trevor Saville Early results of 039 piston are promising 15 psi bump in compression on a stock cylinder and a 7% increase in cut time ... I'm not going to give my full review until I've cut 5 tractor trailer loads of wood with it.
