ABSTRACT:
A fuel system includes a carburetor wherein the throttle valves for the air and fuel are located upstream of the mixing chamber and are moved conjointly to maintain the desired air/fuel ratio over a variation in engine speed. The desired changes in air/fuel ratio can be made by, in one embodiment, utilizing a throttle valve in an auxiliary air passageway whereby more or less air is added to the mixture and too, by providing for the relative angular displacement of the air throttle valve as compared to the full throttle valve while maintaining conjoint movement thereof once the desired air/fuel ratio has been attained.
