Abstract: In at least one implementation a carburetor includes an intake bore with a port opening into the intake bore, a fuel chamber from which fuel is supplied to the intake bore, and an accelerator device including a fuel reservoir. A fuel flow control valve is provided between the fuel chamber and the port to control the flow rate of fuel to the port and at least one passage communicates the fuel reservoir with the port and fuel in the fuel reservoir is supplied to the port therethrough. The passage also communicates the fuel reservoir with the fuel chamber. The fuel flow control valve is located between the fuel reservoir and the port and between the fuel chamber and the port, and the passage includes a portion extending between the fuel reservoir and the fuel chamber independently of the fuel flow control valve.
