Claims

[Scope of utility model registration request]

A venturi formed in the intake passage upstream of the throttle valve, a main fuel passage with one end opening to the venturi and the other end communicating with the float chamber, and one end opening into the intake passage downstream of the throttle valve and the other end communicating with the float chamber. In a carburetor equipped with a slow fuel passage that communicates with the main fuel passage, a main air bleed that guides intake air on the upstream side of the venturi to the main fuel passage, and a slow air bleed that guides intake air on the upstream side of the venturi to the slow fuel passage, An air passage is formed to guide air to the main fuel passage on the downstream side of the air bleed and the slow fuel passage on the downstream side of the slow air bleed, and the passage area of the air passage is controlled based on the atmospheric temperature of the float chamber. Characteristic vaporizer.
