Abstract: The improved carburetor of the present invention provides for direct mechanical control of both an airflow valve and a fuel dispersion assembly such that operation of the airflow valve regulates the amount of air flowing through the carburetor. The fuel dispersion assembly and the airflow valve are mechanically connected by a three bar linkage assembly; the middle linkage being of adjustable length. Mounted within the carburetor is a throttle valve which, when opened, affects the position of the airflow valve. The fuel dispersion assembly comprises a pair of concentric tubes, one rotatable relative to the other and both having one or more radial slots therethrough. A center tube, or "slave" tube, contains fuel from a fuel storage tank. An outer tube, or "sleeve" tube remains affixedly secured to the carburetor. Upon rotation of the slave tube within the sleeve tube, a portion of the slots in each tube overlap, providing a passageway for the fuel, contained in the slave tube, to disperse within the carburetor.
