。 A groove whose cross section gradually decreases from upstream to downstream is provided on the bottom of the piston valve, which is provided in the intake passage so that it can move forward and backward.This groove concentrates negative pressure near the jet needle and nozzle when the engine is running at low speeds, thereby increasing the flow of fuel. A carburetor for improving atomization, characterized in that a notch is provided on the bottom surface of the throttle valve, extending from the upstream side to at least the side surface of the jet needle and being shallower than the groove.
