Need to track down this carb issue

Long time I know, no update. Been wanting to get that fixed lately. I picked up a temporary carb that's too big and runs pig rich, hasn't been that big a deal since I'm just pulling it in and out of the garage for priming and blocking.

I'm leary of investing more money in to it at this point when I can pick up a new Quick Fuel carb and be done with it. Very disappointing.
