Where is the throat of a carburetor?
Air enters through the top of the carburetor (or the side, or the bottom, depending upon the carburetor’s design) on its way to the intake manifold and eventually the combustion chamber of each cylinder. The passage that air passes through is typically referred to as the carburetor’s throat, bore or barrel.
