Default Re: Zenith Carburetor CFM?

BN, we have similar CFMs, and they are in the range of the Number 20 Venturi used in the Model A per the Zenith Company's chart on Vince's site. So I am calling it a 100 CFM carburetor.

I wonder what performance gain would come from using the Model B's Venturi an jet sizes in the Model A's Zenith?
