ABSTRACT:
A two-cycle internal combustion engine includes a crankcase extending from a cylinder and supporting a horizontally extending crankshaft, a piston mounted for reciprocative movement in the cylinder along an axis generally perpendicular to the crankshaft axis, an air and/or fuel inlet on the crankcase including a flange disposed in a first plane extending generally parallel to the crankshaft axis and perpendicular to the piston axis and having a major axis extending transversely of the crankshaft axis, and a manifold having an outlet flange which is disposed in the first plane and has a major axis extending generally parallel to the major axis of the crankcase inlet flange and further having an inlet flange disposed in a second plane extending generally vertically and having a major axis which extends generally horizontally and is angularly related at a substantial angle to the major axis of the crankcase inlet flange. The engine further includes a float type carburetor having a vertically extending outlet flange which is connected to the manifold inlet flange and has a major axis, the carburetor float being operable to regulate fuel flow when the major axis of the carburetor flange is generally horizontal.
In one embodiment, a throttle member for controlling the flow of a fuel-air mixture from the carburetor into the crankcase is pivotally mounted inside the manifold and movement of the throttle member is controlled by an air vane governor mounted on the manifold.
