That 2 barrel carb is a simple rebuild. I had two units and chose the simpler one that did not have a bowel vent, anyway there's nothing in there except a power valve a cheezy accelerator pump and a float valve. In the process I stripped off the pollution canister connections

I blew everything out, wired what ever I could and used carb cleaner on all the passage ways. Dissassemble yours first before you lay out $50 for the kit.

My power valve was working and the accelerator pump diaphram was fine so I bought a separate float valve for $6 and called it good. The gaskets were fine.

The air cleaner stud helps hold the carb top on so don't forget to unscrew it.
