ABSTRACT:
A carburetor for small engines which can be used in all positions utilizes a cylindrical rotary throttle valve with a venturi opening and provides a porous material as a part of the throttle valve, either as the entire material for the valve, or as a sleeve surrounding the venturi portion. During idling the fuel which might collect in a pocket in the valve is absorbed into the porous material and sucked into the engine, thus avoiding the disadvantages of liquid fuel being dumped into the engine when the position of the carburetor is changed.
