ABSTRACT:
A two speed governor for an internal combustion engine includes a flyweight assembly rotatably mounted in a housing. The riser is positioned in the housing and operably connected to the flyweight assembly. The riser is moveable between a retracted position, and intermediate position and an advanced position. A first spring is operably mounted in the housing to bias the riser toward its retracted position when the riser is located anywhere between its retracted position and its advanced position. A second spring is operably mounted in the housing to bias the riser toward its retracted position when the riser is between its intermediate and advanced positions. The second spring has a pre-load but is inoperable when the riser is between its retracted position and its intermediate position.
