Abstract
A low speed idle actuator for an internal combustion engine usable, e.g., in an electrical power generator, can be easily and precisely adjusted to set, adjust, or readjust the low speed idle setting of the engine. The actuator includes (1) an electromagnet including a core and a coil which surrounds the core, and (2) an attractor plate which is connected to the governor lever of the engine. Low speed idle adjustment is performed by axially adjusting the position of the core relative to the position of the coil without moving the electromagnet with respect to its mounts or even loosening the electromagnet from its mounts, thereby adjusting the distance through which the attractor plate travels upon electromagnet energization.
