I have a pk-80 and i blew a piston ring and had to replace the jug, rings, gasket and piston. The piston I got has a "2" on it and is the right bore but the hole that the rod goes through is too big. My original piston has a "3" on it. Does anyone know what the numbers mean and if getting a "3" will fix my problem?
