I love to se a saw piped and working more than a 16 inch bar. I treat my poulan the same way. Ur saw sounds nice and has a distinctive chime to it
I think that's about a 34" bar.. 111 DL of 3/8th skip, whatever that works out to... The difference in exhaust note is because the stinger comes off the belly rather than the end of the baffle, it has a much softer note when placed there because the baffle isn't condensing and amplifying the pressure waves.
I would love to find a lawn boy, though Mastercraft made some 2 stroke mowers too.. I had one for years, it was excellent for mowing hillsides since you could stand on the top of the hill and just one-arm it up and down... Mine was seriously modified.. pretty much the whole front half of the deck was chopped (not Worksafe certified for sure), 2 of the wheels were made of stacked plywood since the plastic ones had long rotted off, and the governor spring had broken so many times it was basically wired wide open.. With the front half of the deck chopped, it meant I could attack wild rose bushes and big clumps of alfalfa, etc and rather than it needing to chop everything fine, it would lop it off at the base.. The ignition died on it and it got tossed.. the 6.5hp briggs can't hold a candle to what that thing could do.
