Thanks for pointing me to that thread. I learned a lot from it, particularly from the Lucas distributor training course that was referenced in one post.
The information makes me think that I have two of the heavy type of spring, whereas the Lucas diagram shows one heavy and one light spring. My hunch is that the original light spring was broken or lost and that a new light spring could not be obtained. Consequently a heavy spring was stretched then fitted to allow some free movement at low revs.
As the car is a standard Ruby, I don't think that the fitting of a stretched spring was a well thought-out performance enhancing trial that might have been attempted on a racing car.
So I guess I should be looking to find and fit a light spring.
