I'm looking for possible options to replace the piston in my Mac PM8200. It's the last of the 82cc Macs and a departure from the previous design in that it uses a three piece crank with circlip style pin bosses for the piston vs. the earlier press fit pins..., which is why none of the other 82cc Mac pistons will work. NOS seems to be non-existent for these things and there weren't even that many PM8200's made, let alone spare parts for em (unless they're hidden in a warehouse somewhere). Production was pretty much at the end of the line for McCulloch as most folks remember McCulloch right about this time. Then it all went south shortly thereafter.
Anyway, any suggestions for 52.4mm piston solutions out there?
TIA in advance for any info or enlightenment.
