Tony, this is a timely warning, as I've just got hold of a pull and spin motor to replace the rather bulky post war one on the car. Unfortunately, the weather here at the moment doesn't encourage me to get the shorts out, long or otherwise.

I do have a quick question though. The motor I have works well, but is permanently on. The knob doesn't move in or out more than a millimeter, which I am assuming it should. I haven't investigated yet, but I am assuming there is a clear on and off position and the knob might be seized on the shaft?

Hi Barry.
There are only two screws holding the back cover on.
Take it off and it will become obvious what happens.
It sounds like you need a bit of WD40 on the spinner as it moves significantly more than 1mm when you pull at it.
When the spinner is fully in, it breaks a spring steel +ve contact due to its lower profile.
When it's fully pulled out, it allows the contacts to come together to send power the points.
Use a neon tell-tale and all should become clear.
The points may need de-greasing and fettling with very fine wet and dry paper.
Smell the ozone as the points spark!
Tony.

Thanks Tony. Sounds like the knob is sized on the shaft or parts are missing then.

Barry, three photos of the workings.
Push knob in and contact is broken, pull out and it's made.
Tony.
