Rebuilding a 032 AV and have a cylinder and piston that I'm going to reuse from another saw. The previous saw had 155 psi before I disassembled it. The piston has no marks on it other than a little carbon on the top. The cylinder looks like a mirror, no marks on the inside. Should I use the cylinder and piston as is or should I run a little scotch bright in the bore and put on some new caber rings?
