    摘要: 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.

    摘要: A primer assembly is provided for use on a carburetor that is vented through an external vent on the primer. In at least some embodiments, the assembly comprises a housing comprising an open end and an outlet with a flexible primer bulb inserted into and closing the open end of the housing, thereby defining a volume within the housing. There is a vent in the primer bulb. A carbon canister is positioned within the volume defined in the housing such that the vent and the outlet are in fluid communication via a flow path that extends through the canister. The carbon canister adsorbs fuel vapors from the carburetor. During normal operation of the engine, air enters through the primer vent and purges the carbon canister of the adsorbed fuel.
