One other thing you might check: see if the spring is making noise against 
the teflon post that is now used instead of bushing cloth around a center 
pin, to hold the rep spring in. I've known it to make a click. To test it, 
you might push out one teflon post and put in a piece of good, 
old-fashioned damper cord, and see if the noise goes away.
