Embodiment Construction

[0029] refer to figure 1 , the carburetor 10 according to the present embodiment has a carburetor main body 12 connected to an intake pipe by means of a connector 11, a cup-shaped fuel chamber 13 connected to the bottom surface of the carburetor main body 12 for storing fuel, and A rotary switch 14 is attached to the fuel chamber 13 for opening and closing the fuel passage and the drain passage.

[0030] Figure 2A A comparative example is shown in which the switch axis is orthogonal to the intake pipe axis. A pair of connectors 111 , 111 is connected to the intake pipe 112 . The central axis 113 of the intake pipe passes through the connectors 111 , 111 . The switch 114 and operating lever 115 are preferably located away from the intake tube 112 so that the operator's hand does not easily access the intake tube 112 . Specifically, the axis 116 of the switch 114 is orthogonal to the central axis 113 of the intake duct 112 .
