Interesting, any pictures or details on what you bought?

It was trial and error. The first set from HF broke. I bought several from Home Depot and cut the spring to length that seemed to give the best tension.

Check the brass throttle arms where the springs rub. The steel spring wears a groove into the brass, which eventually causes it to catch, leading to uneven throttle opening.
both my -12s had to have replacements at around 800 hours.
