Abstract: A carburetor with a housing defining an air intake and fluidly connected to a throttle system is provided. A rotatable choke is connected to the carburetor and includes a plate with an inlet aperture in fluid communication with the air intake. A dial is rotatably mounted to the housing and surrounds a portion of the plate. The dial substantially blocks the inlet aperture when in a first position with respect to the plate, and the dial exposes the inlet aperture when in a second position with respect to the plate.

Abstract: A cylinder-crankcase is disclosed that includes a cylinder block having a cylinder head for receiving a spark plug. The cylinder-crankcase also includes a crankcase and a crank arm for supporting a crankshaft. The cylinder block, cylinder head, crankcase and crank arm are a single, monolithic piece.

Abstract: The disclosed discharge chute directional control system and method is typically used on outdoor power equipment. By moving the position of the handle portion of a spring loaded handle assembly, the operator imparts rotation to a cam assembly. Rotation of the cam assembly imparts opposing forces on a pair of cables. These opposing forces, when applied to the rotational mounting of a discharge chute, change the orientation of the discharge chute.
