る可変ベンチユリ型気化器の供給燃料制御装置。 A needle connected to a suction piston that changes the flow area of the intake passage in accordance with the amount of intake air and inserted into a fuel passage that communicates the intake passage with the fuel reservoir, and a needle that connects the fuel passage and the atmosphere. a bleed mechanism having a control piston forming a connecting bleed passage and changing the flow area of the bleed passage; the needle moves forward and backward together with the suction piston to change the flow area of the fuel passage; and the control piston transmits a negative pressure downstream of the throttle valve in the intake passage to the control piston in a fuel supply control device for a variable vent lily type carburetor that reduces the flow area of the bleed passage when the engine temperature is low. Fuel supply for a variable vent lily type carburetor, characterized in that a delay means is provided for increasing the flow area of the bleed passage when the negative pressure is large and delaying the transmission of the negative pressure to the control piston. Control device.
