Abstract: Engine control assemblies for use with internal combustion engines, engines having such assemblies, and methods for operating such engines and assemblies are disclosed. In one example embodiment of an engine control assembly encompassed herein, the assembly includes a lever structure configured to rotate to any of a plurality of positions ranging from a first position to a second position. The assembly also includes at least one linking structure configured to allow rotational movement of the lever structure to influence at least indirectly an engine choking operation, where the at least one linking structure including a rod that includes a bend portion along its length, and the lever structure includes a formation with an orifice through which the rod extends. The rod and formation are configured so that at least some other rotational movement of the lever structure does not cause any corresponding movement of the choke actuation input structure.

Abstract: A V-twin engine having a crankcase and a pair of cylinders defining a V-space therebetween, wherein the V-space is substantially enclosed, and a carburetor is positioned within the V-space. An intake air preheating arrangement supplies heated intake air to the carburetor, and a carburetor heating arrangement heats the V-space and the carburetor which is positioned within the V-space. Each of the foregoing arrangements, used separately or in combination within one another, aids in preventing “freeze-up” of the carburetor during running of the engine in a cold environment.

Abstract: A secondary engine speed control mechanism for small internal combustion engines, including an operator control which is manually operable to override an engine running speed which is set by the engine's primary speed control mechanism and governed by the governor. The secondary speed control mechanism may be selectively actuated by the operator in anticipation of an increased engine load to provide a temporary increase or “boost” to engine speed above the set, governed engine running speed. The secondary speed control mechanism may be either mechanically or electrically actuated, and may include an operator actuated, trigger-type mechanism or an electrical switch located on the handle of an implement with which the engine is used.

Abstract: An internal combustion engine including a cylinder, a crankshaft, a reciprocating piston disposed in the cylinder and operably coupled to the crankshaft, and a carburetor.
