Claims

[Scope of utility model registration request]

In a fuel supply cutoff device for a carburetor, which has an opening/closing means for opening and closing a fuel passage of a low-speed fuel system that communicates with an intake passage provided with a throttle valve, the throttle valve is closed in a direction from the normal idle opening of the throttle valve. An opening adjustment means for operating the valve is provided, and when the engine changes from the fuel cut state to the fuel cut cover state when the rotation speed decreases to a predetermined value, the opening adjustment means adjusts the opening to the closing direction from the normal idle opening. A fuel supply cutoff device for a carburetor, characterized in that it operates a throttle valve.
