Just an update on this.
I've been working on it here and there and was able to get it running on the original carb. Bought a Chinese version for $11 shipped, but the holes where it bolts to the engine didn't match up. One could be drilled if needed. No big deal.
Anyways, she runs. I need to figure out how the throttle linkages go back together as well as why the recoil rope mechanism squeals, stalls and eventually stops the engine when throttled up.
