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. A secondary air inlet forms an air intake passageway when the main air inlet is closed. The secondary air inlet is defined by a first bore formed in the interior of the elongated tube extending from the carburetor exterior adjacent the main air intake to the central portion of the surfaces. A secondary fuel inlet forms a fuel inlet passageway for mixing with the air in the secondary air inlet. The secondary fuel inlet comprises a second bore in the elongated tube which extends from the fuel reservoir to the central portion of the surfaces. At least one orifice communicates with the bores at the central portion surfaces. A needle is movable with respect to the elongated tube in the first bore for adjusting the flow of the air-fuel mixture through the orifice.
