摘要： PURPOSE:To prevent a main air bleeder from getting clogged due to fuel vapor generated by the rise in temperature, by placing the lower end of a mixing tube above the liquid fuel level in a main fuel passage. CONSTITUTION:A mixing tube 8 is placed above the liquid fuel level in a main fuel passage 7. When the temperature of a carburetor has risen, some of fuel in the passage 7 is evaporated but the fuel vapor does not condense in the mixing tube 8 because its lower end is above the liquid fuel level in the main fuel passage. For that reason, a main air bleeder 9 is kept from getting clogged with condensed fuel. This results in feeding a stable mixture to an engine.

摘要： PURPOSE:To prevent the supply of gasoline from an idle port by providing the various-fuel carburetor for an outboard engine with a means bringing the float chamber of gasoline to a stable negative pressure state under the states of revolution at intermediate speed and high speed. CONSTITUTION:When the revolution of an engine is increased up to intermediate speed and high speed, gasoline pressure-sent by an accelerator pump 29 is discharged into a suction path 12 from the opening 35 of an injection nozzle 34, and revolution is increased smoothly. A suction pulsates at the upstream side of the suction to the throttle valve 14 of the suction path 12 at that time. Negative pressure larger than predetermined value works stably to a second float chamber 24 in the presence of the pulsation of the suction and a check valve 43. Accordingly, negative pressure working to the second float chamber 24 is made approximately the same as or smaller than negative pressure working to the idle port 28 of each suction path 12, gasoline cannot be sucked up into the idle port 28, and uneconomical operation is prevented.
