Abstract
A two stroke cycle internal combustion engine having a closed crankcase adapted to receive a air-fuel mixture and a cylinder extending from said crankcase, a piston reciprocally movable in said cylinder which alternately produces a low pressure condition in said crankcase as it approaches top dead center and a high pressure condition in said cylinder as it approaches bottom dead center, a fuel reservoir for supplying liquid fuel to the air fuel mixture in said crankcase, a bypass passage connecting said crankcase to said cylinder, and a conduit connecting said crankcase to the fuel reservoir for pumping fuel accumulated in said crankcase during starting into said reservoir, and a unidirectional flow control device in said conduit for preventing return flow from said reservoir to said crankcase.
