Just ground back the baffle, opened up the outlet back in behind the deflector and changed the screen to a much more open weave.
It then refused to start and needed a full re calibration.
I am happy with it as is for firewood duty. Myself and a couple friends agree that in this trim it is up there with a ported 044.
One thing I have learnt here in Aus is that American porting numbers dont work in our hardwood.
Saws need to be ported differently here. Speed and RPM is not the winner, broader power band and torque to haul a small sprocket at modest RPM is what we need in super dense hard timber that will melt the tungsten tips out of Stihl chain if you run it too fast. Trust me I have seen it happen
I was interested in what Mr Monkey was doing but wouldn't follow it here in Australia.
I would love to know what basic changes produced more torque like what movements in transfer or what was dont to intake and exhaust porting but I understand if Scott keeps this to him self, He sure wont reply to any PM I ever send him
I have been told on here many times that timber is timber and it wont make a difference but I bet if you put that 28 or 32" bar on your 70cc saw into solid dry ironbark or yellowbox here in Australia, you would be looking for that 20" bar after 1 cut if your not already curled up in the fetal position.
