Ok I picked up one for a song and a dance knowing it wasnt working. I watched so many videos on repair and maintence and I'm ok with mechanics.
I got it home and seen 20 years if just no maintence. Bearing grease on things with hardwood dust caked all over.
As I'm overhauling the machine (and photographing) I came across part 73 which looks like a pen spring. I can see it in the diagram but have zero idea where it goes and how it works.sounds stupid but the speed control came in a box. The spring is making me nuts. I have not came across any video involving this punny spring but I'm willing to bet is needed to use it correctly.
Any help on where this goes and its purpose I will be really happy for. It looks like it goes on the speed dial but not 100 on that.

Welcome to the forum and congratulations. The wire ends of that spring go into two small holes in the Headstock casting beneath the speed indicator dial. The holes are near the top center of the recess for the dial. It provides an anti-rattle function and also a detent feel at two points in the speed range, extremely slow and moderately fast. When the speed control dial is off there is only a bit of friction holding the spring in place, so not surprising when it falls out.

Thank you.that is what I knida thought but was.t sure. Kinda a weird function but it is effective.

Here is a picture showing the spring's placement.
