I've got a complete 365XT in the works, if I can work out a price. Saw is like new but broke a chunk out of the piston, and the guy kept running it until it would not run any more. So the saw will need to be completely disassembled, cleaned and new bottom end bearings and seals installed.
I can do this thing several ways:
New OEM stock C/P converted to 372 by altering the transfer port covers.
New OEM stock 372 XPW 51.4 mm C/P.
New AM BBK with Stihl 064 piston.
New AM BBK with Husqvarna 272XP piston.
New AM BBK with Stihl 038 Magnum piston, requires around 0.008-0.010 removed from the cylinder bottom to get good squish with a gasket.
Whatever the P/C choice saw will use the RWJ-4 carb and intake off a 385 and an unlimited coil. Can do either an HD or standard filter setup. All would also get tuned pipe mufflers.
