Abstract
A rotary throttle valve carburetor includes a main body, a throttle valve and a fuel nozzle. The main body has a main bore with an inlet and an outlet, a valve bore that intersects the main bore and a nozzle opening that communicates with the main bore. The throttle valve has a body received at least partially within the valve bore so that the valve body rotates about an axis and moves axially relative to the main body, and a valve passage therethrough. The fuel nozzle extends through the nozzle opening and into the valve passage, and has a fuel outlet received within the valve passage, an inner surface that defines part of a fuel passage through which fuel flows in the nozzle and to the fuel outlet, and an outer surface that includes a discontinuous portion with a varying radial dimension.
