FAQ
What CFM rating is this carburetor?
750 CFM.
What choke type does this carburetor use?
An electric choke for hands-free, precise cold-start control.
What vehicles is this carburetor best suited for?
Lightweight vehicles running a manual transmission, or an automatic transmission with a high-stall converter and low rear-end gearing.
Why does the finish color vary between units?
The gold dichromate plating process naturally produces slight color variation from casting to casting; this is expected and not a cosmetic defect.
How does this differ from the manual-choke 0-4779C?
It uses an electric choke instead of a cable-driven manual choke; the rest of the specification is the same 750 CFM mechanical-secondary Double Pumper.
