The venturi is cast into the carburetor I believe and I don't believe you can change that. As the carb float bowl has no way of knowing if the fuel is delivered to it by a diaphragm or rotary pump or gravity from a vacuum tank I don't see why it would be necessary to change (if possible) the venturi.

As Troy mentions, if the fuel is delivered at too high a pressure from a fuel pump (3 1/2 to 5 lbs) it can overcome the needle valve and flood the carb
