Throttle return spring

[foot2firewall]

I started to sort out my stretched throttle cable tonight and noticed that the throttle return spring that sits on the vertical spindle (to which the end of the throttle cable connects) is broken and the bottom leg is missing. It's a torsion spring, does anyone know what the offset is on the top and bottom legs (i.e. should they point in the same or different directions) and more importantly any suggestions on where I can get a replacement?

I don't know if this helps, but I found a pic on my phone of my S1:

Thanks, it's a different design on the S3, you can see the spring underneath the triangular plate:

You need to get a straight throttle plate - thats another subject entirely someone will be along soon with a pic.

Voila !



Getting back to springs, this is the little chappie but those sharp bends don't look original to me

Maybe some one in the past has bent it to get a bit more pressure ( sticky throttle???). Where those tight bends are there are signs of wear,it's been rubbing on something, only a matter of time before this one fails.

Thats great philppot, I don't suppose you have a picture of the throttle cable connection behind the plate? On the springs, I've found a company that keeps various sizes of torsion spring in stock - they always come with straight legs, just need to bend carefully to fit.

Not sure where you mean?

On the standard set up or my "de-cluttered" modified version?

Well both would be good, as I can't figure where the spring locates on the plates of the existing layout and the "de-cluttered" version would be a longer term upgrade.

@phillpot: I know I seen this straight throttle plate before here at PH. Did you build it or buy it?

Can't do photo's till get home this evening but to answer Maffe's question I modified a "normal" throttle plate, factory made ones are pretty rare I believe?

[phillpot]

Not a lot to see really...... cable is something like Capri or Mk3 Cortina ? something earlyish before they went to plastic adjusters.
The spring sort of "jumped out" when I took it apart, not too sure how it goes back together. Think I may have another complete assembly somewhere, if I can find it will get a picture or two.



Back to the throttle plate, a bit more of a close up..... the one side was filed out and a fillet made for the other (the "gold" colour is braze)
