CARBURETOR ABSTRACT OF THE DISCLOSURE A carburetor comprising a body defining a throat, a throttle slide member slidably mounted on the body and disposed in the throat, a rotary actuator for the slide member, and a tapered metering rod or needle mounted on the slide member and extending downwardly into a fuel supply tube leading into a sealed and pressurized fuel reservoir or bowl secured to the body. The slide member has front and rear, substantially flat panels disposed in substantially parallel relation, with the front panel being shorter than the rear panel for the purpose of providing air at the outlet of the fuel supply tube even when the slide is in a closed position and for directing air toward and around the outlet when the slide is in an open position. The bottom of the rear panel has a cut-out portion in alignment with the metering rod and fuel outlet at the throat for the purpose of direct- ing high speed air flow toward the metering rod and around the fuel outlet. The metering rod is provided with a downwardly and inwardly tapered, rear flat face and is mounted for longitudinal adjustment relative to the slide member. A shroud surrounds the forward face of the rod adjacent the fuel outlet to reduce turbulence, and an air supply channel surrounds the fuel outlet to promote a balanced system and an optimum fuel-air ratio. - 1 -
