ABSTRACT:
An air and fuel induction system for a two cycle engine having two adjacent horizontal cylinders positioned aligned one above the other and each having a separate closed crankcase includes a single horizontally positioned carburetor having a single metering system for supplying an air and fuel mixture to both cylinders. An induction passageway for each cylinder connects between the carburetor and each crankcase. Each induction passageway has an opening at about the same elevation and each opening has about the same cross sectional area. A reed valve is positioned adjacent the carburetor throat and at the entrance to each of the induction passageways. The reed valve includes at least one flat reed positioned directly across and closing the opening to each of the induction passageways.
