Thought you guys would enjoy this video series from Pat Lacey when he was in Alaska this past summer. When you see the muffler on his saw it looks like just a flat plate on the front instead of the usual Stihl look. Custom front plate?
The saw at some points has like "small twig" sized chips coming out from under that clutch cover... she's a beast
I had asked him on one of his vids who does his mods to his saws and he replied "Olives in Orofino Idaho milled the jug, domed the piston and ported the muffler, I advanced the timing and did the carb swap." Saws always rip!
