ABSTRACT:
An aerodynamic piece (48) for use with a carburetor having a barrel or round slide throttle valve (10). The piece (48) is formed as an Insert which abuts the undersurface (15) of the slide (10). The piece (48) has an inclined bottom surface (28, 31, 32), the amount of inclination (43, 44, 45) being selected to increase the flow rate through the carburetor throat for a given throttle setting. Air flow passing through the carburetor throat hits the surface (28, 31, 32) and imparts a component of upward motion to the fuel (56) passing by the needle valve (11), thereby Increasing the available cross sectional area of the carburetor throat to which the fuel is exposed for atomization. An indented region (38) at the top of the piece (48) permits the use of the piece with a wide range of original equipment slides (10). A size of the pressure drop relief orifice (40) formed within the aerodynamic piece (48) permits the magnitude of the pressure drop across the needle valve (9) to be varied in a linear manner.
