Abstract: A carburetor comprises a mixture outlet and a connection for attaching the mixture outlet to an intake manifold. A main air intake is spaced from the mixture outlet and has a butterfly valve adjustable to control the flow of air into the carburetor. The carburetor also has a fuel inlet. A pair of spaced apart surfaces forms a fuel path from a central portion of the spaced apart surfaces to the periphery of the surfaces. The periphery is adjacent to the carburetor passageway for enabling air from the main air inlet to mix with the fuel and pass to the intake manifold. A central fuel inlet forms a path for fuel from the carburetor fuel reservoir to the surfaces central portion. The central fuel inlet comprises an elongated axially movable tube whose outer surface is tapered. A cylindrical member has its inner surface surrounding the elongated tube outer surface. The cylindrical member and the tube when spaced apart define a main fuel path from the fuel reservoir to the central portion of the surfaces.
