A small air-cooled internal combustion engine includes an aluminum cylinder block at least partially defining an aluminum cylinder bore, an aluminum cylinder head attached to the aluminum cylinder block, and an aluminum push rod tube separate from and press fit between the aluminum cylinder block and the aluminum cylinder head. The aluminum push rod tube includes a cylinder block end portion, a cylinder head end portion, and a main body extending between the cylinder block end portion and the cylinder head end portion.

An engine assembly includes a crankcase, shaft, blower housing, and cooling fan. The shaft is rotatably coupled to the crankcase and defines a rotational axis. The blower housing includes an internal space. The cooling fan is disposed within the internal space, includes a plate defining an upper surface, and is positioned to rotate with the shaft about the rotational axis. The cooling fan includes a band having an inner band radius and an outer band radius. The cooling fan includes a plurality of reversed fins extending between the band and the upper surface and between a root adjacent to the rotational axis and a tip adjacent to the outer band radius, each fin offset at an angle measured in a counterclockwise direction from a plane passing through the rotational axis and the tip to a plane passing through the root and the tip when viewed from above the cooling fan.

Engine

An air/fuel mixing apparatus, configured for use with an internal combustion engine, includes a body defining a passageway therein, a throttle lever including a cam surface, a throttle valve positioned in the passageway and responsive to movement of the throttle lever, a choke lever including a follower surface configured to be engaged by the cam surface, and a choke valve positioned in the passageway and responsive to movement of the choke lever and the throttle lever. The air/fuel mixing apparatus also includes a solenoid configured to disengage the choke lever from the throttle lever, and move the choke valve to a substantially-opened position.
