Charlie, or anyone else...
I have a pal who does any imaginable spring in any quantity, from medical pacemakers to mine elevator springs and anything in between.
He supplies all my choke return springs, accelerator fulcrum springs and throttle speed springs, all heat-treated 302 stainless.
Don't laugh, but he has a degree in Spring Engineering.
Have a peek at his website: www.springworksutah.com
If you'd like a quote, just send me a sample and/or a good description. Everything is CNC and kept in a file, so if I go back for more in 10 years, I get the same thing... Did I mention he did the valve springs for the recent restoration of the Mormon Meteor?

I will install a slightly weaker or stiffer spring depending on the the pressure
readings or failing that the lever or base....I never really know. Can't beat
real world testing.
