燃料流入口下方のウェル内に連結したエアバルブ式An air valve that is controlled to open and close by the intake air flow is provided in the intake passage of the secondary side carburetor, an acceleration fuel well is formed on the side of the intake passage of the secondary side carburetor, and the fuel is vaporized through the throttle. A pick-up tube for supplying accelerated fuel connected to the well and extending in a substantially vertical direction is inserted into the well so that a fuel inlet of the tube is opened into the fuel in the well, and a fuel outlet of the pick-up tube is connected to the well. In the air valve type carburetor, which opens into the intake passage between the air valve and the secondary throttle valve, when the opening of the air valve is less than a predetermined setting, the air valve opens into the intake passage upstream of the air valve, and the air valve opens into the intake passage between the air valve and the secondary throttle valve. A fuel supply port that opens into the intake passage downstream of the air valve when the opening is greater than or equal to the opening degree is formed on the inner wall surface of the intake passage of the secondary side carburetor, and the fuel supply port is placed in the well below the fuel inlet of the pickup tube.
