Hi EB,
I marked everything with an indelible marker before I took it all apart: eccentic, sprocket, chain. I lined the pin up to fit the "before" configuration and checked to ensure piston 1 was @ TDC. The pin was @ 12:00, but I don't know what timing mark you are referring to, that is supposed to be at 1130. Can you clarify? Thnx...Rusty
