Claims (1)

[Scope of utility model registration request] A starting fuel supply passage, one end of which opens into the main fuel supply passage connecting the fuel tank and the carburetor, and the other end of which opens into the intake pipe after the main jet opening of the carburetor vent, and an outside temperature-sensitive fuel supply. In the starting fuel device, the outside air temperature sensitive fuel supply means is provided in the middle of the starting fuel supply passage, and when in the standby position, an air vent passage that opens at the top of the fuel tank and the starting fuel supply means are provided. A rotatable fuel reservoir that communicates with one end of the starting fuel supply passage and stores a certain amount of fuel, and when set to a rotational position, supplies fuel according to the rotation angle from the oil reservoir to the starting fuel supply passage. a member having a fuel reservoir that overflows from the other end; and a suction pipe that is provided in the middle of the starting fuel supply passage and outputs a mechanical displacement amount in response to the temperature of the suction pipe and/or the gas within the suction pipe. and a temperature displacement converting means provided in the starting fuel supply passage, which is directly connected to a member in which the fuel reservoir is provided, and cooperates with the mechanical output of the temperature displacement converting means to convert the fuel reservoir. 1. A fuel supply device for starting a general-purpose engine, comprising: an automatic return type rotation means for controlling a rotation angle; and a fuel supply device for starting a general-purpose engine.
