Abstract
The present subject matter relates to arrangements and uses for engine speed governors. In particular, an automatic idle system for a small engine can include an engine speed governor for connection to a small engine with a governor shaft rotatable in response to a speed of the engine. A governor linkage can include a first portion for connection to the governor shaft and a second portion for connection to a throttle control of the engine, the first portion being movably connected with or to the second portion. An actuator can be connected to the second portion of the governor linkage, the actuator being movable in response to a load on the engine to move the second portion relative to the first portion. In this configuration, when the engine is in a low-load state, the second portion can be moved relative to the first portion toward a throttle-closed position.
