Illustrated Parts List
This is about at close as I could find for your engine. I don't know why B&S doesn't make there IPL more 'user friendly' to look-up.
As far as the thing reving up, and won't idle back down, I would start looking with replacing the airfilter ref. #445 for sure. And look at your throttle shaft ref. #131 itself... is probably worn out (and sucking air). There is a little plastic bushing ref.#93 on the throttle shaft, that may be loose or worn, & the t.shaft seal ref#987 should be replaced, also the choke shaft #141 may need some attention, both of those shafts need to be sealed well to prevent dust & dirt from entering the engine. They should be able to rotate easily, without binding, but not 'rock around, back & forth'...which indicates worn-out shafts. A common problem.
As far as the extra spring that doesn't do anything~~~ your probably finding the governor linkage spring (ref. #232, find in the Alternator/governor group)is broken on one end or came loose. Oft times that spring can be reformed on the broken end & reattached, but a new one might be necessary.
A new fuel filter & clean out the carb. bowl, just for fun, and you should be idling back down as normal.
