Due to the driving action of the helical gearing, the distributor drive shaft tends to push upwards. This distributor drive shaft spring ensures that the drive shaft stays in place.
When adjusting the ignition, the clamp has to be loosened to turn the distributor. At that moment the drive shaft gains room and tries to push upwards. To prevent this, the drive shaft is kept under tension with a spring between the drive shaft and the distributor. Without this spring the drive shaft is no longer held under tension.
Not only the absence of the spring, but also a spring with too little spring tension can cause trouble. We therefore recommend replacing the spring during overhaul work.
