Abstract
An air valve type two-stage twin compound carburetor for an internal combustion engine comprises a carburetor body including a primary bore and a secondary bore, a primary throttle valve which is arranged in the primary bore so that it can be opened and closed, a secondary throttle valve which is arranged in the secondary throttle bore so that it can be opened and closed co-operatively with the opening and closing of the primary throttle valve after the primary throttle valve has been opened beyond a certain degree, and an air valve which is arranged in the secondary bore upstream of a secondary fuel nozzle disposed upstream of the secondary throttle valve, so that the air valve is opened and closed. The degree of opening of the air valve is regulated so as to be opened when the primary throttle valve is in the idle closing position or in the initial opening position.
