Rebuild current Carb or new carb altogether

I have the same question for my '64 Barracuda, running super rich, let me know how the rebuild or new carb works, or of if I do it first will post. There is a good Uncle Tony's Garage video on the Chinese knock-offs and their shortcomings, specifically the Carter 2-BBl on his '65 Barracuda 273, as I recall. Jamie on Dead Dodge Garage says they frequently leak gas at main throttle shaft on driver's side so that could be a consideration, too.
