My accelerator pump is not working, and it's not needed, because I have quite small primary venturi on my carburetor.
Smaller venturi atomizes fuel better on lower rpm.

I like the idea, but I am not aware of a commonly available carburetor in 2 barrel configuration that is spread bore, or said another way, small primary and large secondary. 4 barrel carbs can be had this way, and I have one waiting for later stages, that is configured this way. Do you know of a staggered 2 bbl carb?
