ABSTRACT OF THE DISCLOSURE Icing trouble with two-cycle engine carburetors can be effectively avoided by the provision of an engine-lubricating- oil nozzle in the carburetor opening into the intake air passage therein at a point adjacent to the fuel nozzle opposite to the throttling end of the piston type air throttle valve so that an oil film is formed on the exposed surfaces of the throttle valve and the needle valve associated therewith to control the rate of fuel discharge into the intake air passage. Any ice which may be formed on the valve surfaces readily exfoliates, and thus does not cause any sticking of the throttle and needle valves in the carburetor.
