Claims

[Scope of utility model registration request]

An air valve device that controls the amount of air flowing in the secondary intake cylinder when the throttle valve is fully opened, an acceleration fuel passage 9 that communicates the float chamber 4 and the acceleration nozzle 11 via the fuel reservoir 7, and the fuel reservoir 7 and the atmosphere. In a two-barrel carburetor having a communicating atmosphere passage 12, an air valve 13 is connected to the accelerator passage 9 so that it is located above the air valve 13 when the opening degree is below a predetermined opening degree, and the air valve 13 is positioned above the air valve 13 when the opening degree is below a predetermined opening degree. This fuel auxiliary device for a carburetor is characterized in that an air hole 10 is provided in a secondary intake cylinder 15 so as to be located below an air valve 13 when the temperature exceeds 50°C.
