I have motor almost completely disassembled now. I have dremel and it has lot of job soon Theres quite lot angles to round, casting is rough and bumpy. If I have go oversized pistons, do i have to bore cylinders? Manual says piston ring gap has be about 0.8mm but where I measure it
Also noticed that all cylinder holes are unfinished sharp edges with 90 angle. There should be bevels or roundings to save piston rings.

I take more pics parts later today, before do anything else than planing the head.

Where to get power reeds or material to make them?
