Abstract

A carburetor provided with a fuel flow rate control device (11) disposed midway in a fuel passageway between a fuel pump (8) and a metering jet (4); a level sensor (13) arranged in a passageway (12) for detection connected upright to a portion between the fuel flow rate control device and the metering jet provided in the fuel passageway; an electrical control circuit operating the fuel flow rate control device in accordance with the output delivered from the level sensor so that the level of a fuel column to be formed in the passageway for detection is maintained at a predetermined positon, in order to enable fuel supply with permanent stability to be performed without using a float chamber or without being affected by the vibration of the engine and the turn of a car body.
