I have two 2100s. 1.01 - 50 jets 1.14 - 52F jets

On the same engine, what is the difference between running a larger venturi with smaller jets vs a smaller venturi with larger jets?

Smaller venturi = better throttle response and better fuel mileage.

Larger venturi = higher rpm capability before engine "runs out of air".

Jets is a non-issue. They simply need to be sized to properly deliver the correct air/fuel mixture.
