My first thought is the front of the repetition lever hitting the hammer rail. Second, either end of the butterfly spring. The end may be catching on the jack or the wire may be bent wrong. Third, glue may have oozed out from under the key end felt rubbing the next key. I have found all of these from time to time. Jon Page Cape Cod.
