Hey Guys I recently replaced the top end on an older 372xp I thought I had seized the piston. When I removed the head I broke the rings. As a quick fix I bought a head piston assembly and attached. When I went to fire it up it started and ran. Quite loudly then shut down. Flywheel seems to have locked up. I took the plug and the pull start off and shot some wd40 in the head to lube it and manually turned it over it keeps seizing up in different spots then it would turn over freely then lock up again. Is this a bearing issue??
