Abstract: Fuel porting and passage arrangements including transfer porting and passages between the crankcase and the combustion side of the piston, together with intake porting and passage arrangements for delivering fuel to the crankcase. The transfer and intake passages include portions of regions common to both or in communication with each other in relationships providing not only for direct delivery of fuel to the crankcase but also for augmenting fuel transfer into the combustion space.
