ABSTRACT:
An assembly is provided for supplying a supplemental source of ambient air into the air intake manifold of a two-cycle internal combustion engine during start-up and abnormally low idle modes during which typically only minimal air would otherwise be available. Upon increase of engine speed, the supplemental ambient air flow is stopped. In one embodiment, a flow path is provided between the crankcase of the engine in order that puddled fuel will be bled from this location and to the location of the supplemental air inlet in order to thereby recycle and burn the puddled fuel during high speed operation of the engine.
