ABSTRACT:
Icing troubles with carburetors of two-cycle engines can be effectively avoided by the provision of an engine-lubricating-oil nozzle arranged in the carburetor and opening into the intake air passage therein in a position adjacent to the fuel nozzle in opposing relation to the throttling end of the piston type air throttle valve so that oil films are 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 possibly formed on the valve surfaces readily exfoliate, not causing any sticking of the throttle and needle valves in the carburetor.
