All the gear and no idea...Hard core saw men, only use carburetors. Those fuel injections use micro processors, that cannot be adjusted with a tiny screw driver and therefore are prone to failure in mid cut.
I'm fully convinced that if Stihl were to put a little screw head on top of the saw, with an arrow pointing to more power, that would increase sales by orders of magnitude. Of course the screw head need not be attached to anything, but would rotate freely with a Professional Only screw driver, available only thru authorized dealers.
Doesn’t know how to tune a chainsaw needs safe place little orange screwdriver bad!
