HELP rebuild my carter or buy new eddie ?????? 340

I'd rebuild the AVS. The factory put a lot of time and testing in calibrating that carb for your engine. Rebuilt and set up properly they run great. Choke should work fine with the flapper open. I take mine completely out and seal the holes. Of course I don't live in South Dakota anymore.
I'm with 66... rebuild and fix the choke and drive on.
