FIG. 1 is a sectional view of a carburetor for an outboard motor according to the present invention. Figure 2 shows the low-speed fuel outflow hole, the fuel flow rate and total fuel flow rate (solid line) of the first and second fuel nozzles of the outboard motor carburetor of the present invention, and the main fuel nozzle of the conventional outboard motor carburetor. Fig. 3 shows the qualitative relationship between the fuel flow rate (dashed line) and the throttle valve opening. FIG. 3 is a diagram showing a qualitative relationship between the rotational speed of the outboard motor and the rotational speed of the outboard motor. Explanation of symbols: 1...
