When power is applied to starter electric solenoid moves
drive pinion out onto drive shaft and into mesh with
fl ywheel ring gear. When pinion reaches end of drive
shaft it rotates fl ywheel and cranks engine.
When engine starts and start switch is released, starter
solenoid is deactivated, drive lever moves back, and
drive pinion moves out of mesh with ring gear into
retracted position.
