<p>CARBURETOR A carburetor comprising a body defining a throat, a throttle slide member slidably mounted on the body and disposed in the throat, and a tapered metering rod or needle mounted on the slide member and extending downwardly into a fuel supply tube leading into a 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 the outlet when the slide is in an open position. The body is provided with a substantially axial groove intersecting the fuel outlet at the throat for the purpose of directing high speed air flow toward the metering rod and over the fuel outlet when the slide is opened. 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.</p> |
