ABSTRACT:
The starting system allows small engines having electronic governors to be powered by an alternator, thereby eliminating the need for a battery or a manually-operated start lever. The starting system causes the throttle to be in the Wide Open Throttle position at engine starting speeds. The starting system disengages at engine running speeds above about 1200 RPM. The starting system includes a pivotable lever arm, a spring that biases the lever arm in a first direction, and a centrifugally-responsive flyweight assembly that moves the lever arm in the opposite direction. At engine starting speeds, the spring force is greater than the opposing force applied by the flyweight assembly, causing the lever arm to engage a governor arm and to open the throttle to the Wide Open Throttle position. At engine running speeds, the opposing force increases and overcomes the spring force. At that point, the lever arm disengages from the governor arm, allowing the governor to position the throttle without interference from the starting system.
