化器。 A bypass fuel passage is branched from the fuel passage upstream of the metering jet, and the bypass fuel passage is connected to a bypass fuel outlet opening in the mixing chamber between the suction piston and the throttle valve, and the fuel passage upstream of the metering jet is ignited. The variable bench lily is connected to the atmosphere through an on-off valve that responds to an ignition switch, and opens the on-off valve when the ignition switch is turned off to prevent fuel from flowing out from the fuel passage. In the carburetor, a bypass fuel suction passage is branched from the bypass fuel passage at a position adjacent to the bypass fuel outlet, the bypass fuel suction passage is connected to a negative pressure generation region, and an ignition valve is provided in the bypass fuel suction passage. A variable bench lily type carburetor is provided with a fuel suction control on-off valve that responds to the ignition switch so that the fuel suction control on-off valve is opened for at least a certain period of time after the ignition switch is turned off. vessel.
