Weber throttle return spring
Having got my 32/36 working over its full range I am finding that the throttle (cable) wont close off properly and sits at 1500 rpm until I stab the
throttle pedal a couple of times.
Its in bits at the moment to be well lubricated and I have also found a way to add another spring, but its a bit of a bodge 
I thought I would treat it to a new standard return spring which is 30 years old and probably weaker than it should. Can anyone help me locate one - I
have done the normal E bay stuff.
Better still can anyone recommend a stronger version of the same spring?

Couldn´t you try to Shorten it a bit, and bend new end?
This way you would gain some "springyness"

Beware of what you wish.. for it may come true....

My knowledge of metallurgy is limited, but I'm not sure it would bend without being heated and then I don't know if it would retain
it's spring like characteristics.

Thanks for hunting that out, but its subtly different to mine, having one curved end and one flat. Whereas mine has two curved ends, which are also at
different angles.

Cleaned and lubricated the cable without any improvement  Also re-routed it to give the gentlest sweep.
It seems that to stop it revving I have to put my foot under the throttle pedal and lift it a bit. Aside from a tiny spring on the Weber, it looks
like the return spring I have shown is the only one, and its job seems also to have to lift the pedal, which it's sadly failing to do.
I think my pedal box was off the Sierra. Is it normal to have no return spring on the pedal itself?

I have twin 40's and floor mounted pedals but have a look at the last photo in my archive (I can't resize photos at the mo).
It is a return I made for the pedal. The bulkhead/footwell goes in-between the two washers. Works brilliantly in conjunction with the two return
springs on the carb linkage.

I cant quite work out where you install that. It looks like it pushes rather than pulls, so does it attach to the lower part of the pedal, between
pedal and bulkhead?

Yes the clevis attaches to the pedal and the springs push against the bulkhead when you press the pedal, thus returning the pedal to it's normal
position.
It is made of a nylock, a nut, two washers, spring, clevis and a piece of bar threaded at each end.
I'll take a picture of it in place next time I'm in the garage.

Ah, no,. a return spring on the pedal end would be a good plan
