All of them= are possibly valid but precious few are actually likely. Process= of elimination still works very well in diagnosing problems.

I suggest you look very carefully at= whether or not you have too much glue in there. It will have= dripped down lower in the mortise than the felt and could be= rubbing against the key pin when the key is depressed. If you= thought that the problem was in the felt and you eased the= bushing you may have missed it. What type of glue did you use?= Look carefully at each key mortise under a strong light and I'll= just bet you'll find a glob of glue in there.
