Model 87 - 1 Barrel

The 87 series carburetor is of the single barrel horizontal design with twin floats and a single venturi built integral with the throttle body casting. The carburetor is of the balanced type in that all air for fuel bowl ventilation, metering well ventilation and idle operation must enter through the air cleaner. Since the metering well surrounds the discharge jet and the main jet (which are both centrally located), operation at extreme angles in any direction is permitted. The fuel supply system consists of the fuel inlet fitting, fuel valve, needle & seat, twin floats and the float chamber. The idle system consists of three idle discharge holes, idle adjusting needle, idle air passage, idle air bleed, idle jet and idle fuel pick-up passage. The high speed system consists of the venturi, main discharge jet, well vent jet, metering well, main jet and main jet adjustment. The choke system consists of the choke plate, choke shaft and external choke lever.
