A fuel control apparatus in the form of a carburetor which includes a hollow shaft mounted transversely within the carburetor throat with the ends thereof extending externally of the carburetor so that a throttle control lever can be attached to one end while the opposed end threadingly engages a stationary needle valve assembly. A butterfly valve element is affixed to a medial length of the shaft. Ports are provided adjacent to the butterfly and a seat is located between the needle valve and the ports so that as the throttle moves the butterfly valve, the needle valve element is moved toward or away from the seat. A fuel flow passageway is provided through the needle valve and into an annulus formed within the shaft and upstream of the seat so that when the valve element is displaced from the seat fuel can flow therethrough, into the medial portion of the hollow shaft, and through the fuel ports thereof.
