In the drawings, Figures 1 and 2 are a top view on the fuel pump side and a side view on the fuel needle valve side of a conventional example in which the throttle valve shaft and the choke valve shaft are respectively sectioned on the surface of the carburetor body, and Figure 3 is a side view on the fuel needle valve side.
The figure shows a front view on the throttle valve side of a conventional example. Figure 4 is the third
The throttle valve adjusting arm when the throttle valve is fully closed and the throttle valve operating arm when the throttle valve is fully open are shown as seen from arrow A in the figure. Fifth
The figure shows the throttle valve operating arm when the throttle valve is fully closed, as seen from arrow B in FIG. Figures 6 and 7 are a top view on the fuel pump side and a side view on the fuel needle valve side of an embodiment of the present invention in which the throttle valve shaft and the choke valve shaft are respectively sectioned on the surface of the carburetor body, and Figure 8 is a side view on the fuel needle valve side. The throttle valve side front view of the example is shown.
FIG. 9 shows the throttle valve arm when the throttle valve is fully closed and the throttle valve arm when the throttle valve is fully open, as seen from the direction of arrow C in FIG.
FIG. 10 shows the interlocking state of contact between the choke valve arm when the choke valve is fully closed and the throttle valve arm when the throttle valve is opened when the throttle valve is started, as viewed from the direction of arrow C in FIG.
