Of course the very large ones do, but even the smaller ones (who participate with Ace Hardware) do in my area. They include a number of very small springs - this way you can feel the strength of the various sizes. As an alternative, if you want to do mail order is to get a pull-scale (like a fish scale) at the scale you want (a postage scale?) and then connect it to the mechanism. You can get an accurate measure of the pull you need from that and many springs are sold with that information. There are also ways to calculate the strength of a spring knowing its wire diameter and the diameter of the coil, but it is not a casual calculation if you haven't had a class on it. Personally, for a puppet, I would rather just play with the various spring sizes rather than do the calcuations. I suspect there will be charts for standard sizes though. Contact me if you are really interested in this and I will put more effort into looking for something like this.
