Number of Carburetors
What you do:
Choose the number of carburetors you need to optimize air flow and weight.
Factors to consider:
carburetor weight = carburetor cfm + 5
If an engine has a carburetor, no throttle body is needed. If an engine has a throttle body and a carburetor, the smaller of the two will dictate air velocity. If an engine has a throttle body and no carburetor, it is assumed the engine is fuel injected.
