More digging, I discounted a burnt 201t thinking it’s just a junker and only good for parts. However @trains said not to discount it so I took the muffler off and the piston is mint. This p&c may go on the scored but good looking 201tc. My concerns are the transfer port covers. They’re glued down aren’t they? Maybe best to try save the non burnt 201tc cylinder and just put this piston in? Any advice much appreciated. I’ll check the rubber lines in the clutch area to see how bad the fire got…
