Abstract
An all-position carburetor having an air fuel mixing passage with a rotary throttle valve rotatably disposed in the carburetor body across the mixing passage. The throttle valve has an opening therethrough to provide a venturi passage in conjunction with the mixing passage. A by-pass groove is formed in the outer surface of the rotary valve on the bearing surface of the body to allow fuel which might otherwise accumulate in a pocket, in certain positions of the carburetor, to flow into the main air fuel mixture, thus avoiding overrich conditions when the carburetor is turned from one position to another.
