Fig. 1 shows an embodiment of the present invention; Fig. 2 is a sectional view showing the throttle valve in an open state; Fig. 2 is a sectional view showing the throttle valve in a closed state; and Fig. 3a shows the operating state of the engine. Figure 3b shows the control width of the air-fuel ratio and the change in float chamber pressure with respect to the duty ratio of the solenoid valve opening/closing control when the engine is in the slow range. Figure 3c shows the control width of the air-fuel ratio and the change in float chamber pressure with respect to the duty ratio when the engine operating condition is in the power range. 4 are diagrams showing changes in the control width of the air-fuel ratio with respect to the amount of intake air. 15... Slow port, 21... Float chamber,
22... Solenoid valve, 32... Second fuel passage, 36... Air control passage.
