So I bought an inexpensive 7hp saw and 32" bar. I am working with filthy wildfire destroyed trees so gunking up an expensive saw made no sense. Actually got the saw a few days ago. Took a couple days to figure out the carb tuning at 9000' altitude.
Makes cutting stumps at ground level 10 times easier. I find the weight of the saw kind of helps with felling. No need for a big saw when bucking. All my saws noodle when bucking - most struggle when felling larger trees.
So happy with the big saw I bought a 72cc saw with 28" light weight bar tonight. I love saws and guns it seems.
A few things that will help a lot. Pull the flywheel and file the leading edge so the flywheel can advance a little. Pull the cylinder and remove base gasket. Use regular gasoline. I have a 372 XP which is about same size. I works well on limbs and small trees. Thanks
