ABSTRACT:
A variable venturi carburetor is disclosed which has side walls that simultaneously are moved toward and away from one another to increase the size of the throat of the venturi as the engine speed increases and decrease the size of the throat as the engine speed decreases to provide a desirable constant air-to-fuel ratio to the engine over a range of engine speeds.
