Abstract:

An engine includes a stationary member, a crankshaft supported for rotation by the stationary member, and a flywheel rotatable in response to rotation of the crankshaft. A fan has a plurality of fins and is rotatable in response to movement of the flywheel. A movable air vane includes a surface that deflects air from the fins as the fins move with the flywheel. The engine also includes an intake passageway for intake air and a throttle lever including a throttle pivot point and a throttle linkage aperture. The throttle linkage aperture and the throttle pivot point define a first axis having a first side and a second side. A throttle valve is disposed in the intake passageway to control the flow of intake air. The throttle valve is movable in response to movement of the throttle lever. A throttle linkage is positioned to directly or indirectly connect the air vane and the throttle lever.
