摘要： A carburetor having an inlet opening that includes a pair of concavities operative to direct air toward the metering rod of the carburetor. A carburetor having an inlet opening that includes an arcuate manifold adjacent to the inlet opening and in fluid communication with a fuel reservoir. A carburetor having a slide assembly that includes a positioning mechanism operative to adjust the position of the metering rod relative to the throttle slide. A throttle slide that includes a flow guide that bisects an arcuate relief on an underside thereof. A method for configuring the throat of a carburetor that includes an upper portion of a first diameter and a lower portion of a second diameter that is offset from the first diameter. The method comprises deriving an optimum size for the first and second diameters and the offset based on the pumping efficiency and operating parameters of the engine.

摘要： A two-cycle engine for boosting intake pressure for higher performance per displacement. The two-cycle engine includes a crankcase having a blower housing and a crankshaft therein extending through the blower housing. The blower housing has an intake opening and a discharge opening. An impeller is disposed around the crankshaft. At least one cylinder is provided with a corresponding piston therein. The cylinder has an exhaust port located on a side wall of the cylinder. An intake conduit extends along the side wall of the cylinder in a spiral rising towards the top of the cylinder and passing beneath the exhaust port to terminate at a pair of intake ports in the side wall of the cylinder. A boost plenum has an intake tube fluidly connecting the discharge opening of the blower housing to the boost plenum. The boost plenum also has a discharge tube fluidly connecting the boost plenum to the intake conduit.
