摘要：
An idle fuel supply device for a carburetor has an idle air passage (2) that communicates with an air intake passage (30) and a fuel chamber (27). A passage (2) extending from a fuel metering chamber (13) is connected to the fuel chamber (27) preferably via a fuel adjusting needle valve (31). A low speed fuel nozzle hole communicates the fuel chamber (27) with the air intake passage (30) in the vicinity of a throttle valve (24) when in its idle position. A passage communicates with the fuel chamber (27) and the idle air passage (2), so that fuel and air may mix in at least a portion of the idle air passage (2).
