I got mine back together after repairing a hogged-out AV bracket, it is a cool saw. Seemed to bog down rather easily with a 25" bar in a big red oak, though. Maybe some tuning to be done. The H screw burbles at 1/2 turn out, so not sure what that is about. It does go through some gasoline, but is has a really cool sound! It really barks at you. I like it enough that I may stick it in the Duplicator® to see what happens.........
