Well, it seems as though the red spring is no longer able to keep pressure on the centering cone as I move the stick off center. Once I move the stick off center, the centering cone remains raised and it's as if I have no spring installed. I'm thinking some type of lubricant on the shaft to allow the centering cone to slide up and down the shaft *may* keep it from sticking. Perhaps a stronger spring, but, I liked the feel of the red better than the rest.
