I have a Gravely two wheeled 5665 commercial with 12hp k301.
Im rebulding the engine now. He Is bored at .010 over. I need a new rings kit and here in Quebec it's not easy. I can have one from stens 500-827.(https://www.stenscanada.ca/500-827-piston-rings-010)
I want to know if is the good one for my engine because I don't have the serial number off the engine.
