I didn't know that. I thought that part would be a hard one to scrounge. I ended up welding it with some "white metal" and propane torch. However, after all that, cleaning the carburetor, adjusting valves etc. I started it up and there was this clunking sound. It was worse on start-up but I could still hear it a little when it was idling. It got worse again on any acceleration. I think it is a bearing. What do you think? Tossing up whether to have a go at it.
