Abstract:
1. An engine comprising: a stationary member; a crankshaft supported for rotation by the stationary member; a flywheel rotatable in response to rotation of the crankshaft; a fan having a plurality of fins, the fan rotatable in response to movement of the flywheel; a movable air vane having a surface that deflects air from the fins as the fins move with the flywheel; an intake passageway for intake air; a throttle lever including a throttle pivot point and a throttle linkage aperture, the throttle linkage aperture and the throttle pivot point defining a first axis having a first side and a second side; a throttle valve disposed in the intake passageway to control the flow of intake air, the throttle valve movable in response to movement of the throttle lever; a throttle linkage positioned to directly or indirectly connect the air vane and the throttle lever, the throttle linkage and the movable air vane disposed on the first side of the first axis; and a resilient member directly or indirectly connected to the stationary member, and to the throttle lever at a resilient member aperture that is located on the throttle lever on the second side of the first axis, the resilient member configured to apply a force to bias the resilient member aperture in a first direction away from the flywheel.
