ABSTRACT:
Disclosed is a variable venturi type carburetor comprising a movable suction piston. The suction piston has a needle entering into a stationary jet. The needle and the jet defines an annular opening through which the fuel is injected into the intake passage formed in the carburetor. The jet is connected to a fuel reservoir via a fuel supply passage. The fuel supply passage is connected to the atmosphere via an air bleed passage. A bubble generating pipe made of sintered metal is disposed in the fuel supply passage at a position in which the air bleed passage opens to the fuel supply passage for creating fine bubbles of air in the fuel.
