。 A power valve opens and closes a power system fuel passage that supplies fuel in the float chamber to the main nozzle when the power piston operates, and a pressure chamber and intake valve into which intake negative pressure is introduced via a negative pressure passage that communicates with the intake passage. A negative pressure actuator that operates the power piston with a diaphragm that defines a pressure chamber with the other pressure chamber into which negative pressure or atmospheric pressure is introduced and that is displaced according to the pressure difference in these pressure chambers, and a negative pressure actuator that detects the temperature of the engine. 1. An air-fuel ratio correction device for a carburetor, comprising: temperature detection means; and switching means for switching between introducing negative suction pressure or atmospheric pressure into the other pressure chamber in accordance with the temperature of the engine.
