Abstract: The invention provides a fuel feed system for an internal combustion engine, the system including a fuel pump, a vapor separator including a fuel chamber having an inlet and an outlet and being adapted to contain a supply of fuel, the vapor separator including a float valve and a passage for venting fuel vapor from the chamber when the supply of fuel is below a predetermined level, and a vapor pump communicating with the passage and a source of cyclically varying pressure for pumping fuel vapor from the vapor separator and to a location remote from said source of alternating pressure, the fuel vapor pump operating independently of the fuel pump.

Abstract: An internal combustion engine comprising an engine block including a cylinder and a combustion air passage for supplying combustion air to the cylinder, an air silencer communicating with the combustion air passage, and an elastic connector for securing the air silencer to the engine block.

Abstract: An internal combustion engine comprising an engine block including first and second cylinders and first and second combustion air passages for supplying combustion air to the first and second cylinders, respectively, a first carburetor communicating with the first combustion air passage, having therein a first opening, and including a first fuel supply passageway communicating with the first opening, a second carburetor communicating with the second combustion air passage, having therein a second opening, and including a second fuel supply passageway communicating with the second opening, and a fuel manifold including an integrally molded first manifold portion comprising an elongated portion defining a first main passagewy having a closed end and an opposite open end, and a first nipple portion defining a first nipple passageway communicating betwen the first opening and the first main passageway and extending transversely to the first main passageway, and an integrally molded second manifold portion compris

Abstract: An engine apparatus comprising an internal combustion engine including a timer plate including thereon a throttle controlling cam, a carburetor mounted on the engine and including a throttle valve, and an actuating lever operably connected to the throttle valve, a cam follower assembly including a rocker arm pivotally mounted on the engine and having an end, a roller rotatably mounted on the rocker arm end and including an outer surface, and an abrasion resistant sleeve member on the roller outer surface, a spring biasing the cam follower assembly for engaging the sleeve member in rolling contact with the throttle controlling cam, and a link connecting the rocker arm to the actuating lever for actuating the throttle valve in response to movement of the timer plate.
