Abstract
A single control for manipulating a fuel valve, a choke condition, and an ignition system condition of an engine of a portable engine powered device that simplifies starting, stopping, and operation of the engine associated with use of the device. The control includes a dial that can be rotated to positions between a first radial position and a second radial position. When the dial is in the first radial position, the fuel valve is maintained in a closed position and the ignition system is grounded such that the engine is rendered inoperable. Rotation of the dial away from the first radial position completes the ignition circuit, opens the fuel valve, and initiates a choke position suitable for subsequent starting and self-sustained operation of the engine. The dial is also axially displaceable to activate an electronic starter for engines so equipped.
