Worn out buckskin?

The customer complained about one key (2nd Eb above middle C) not working. The problem was that the jack would get stuck when the hammer returned. I tried various regulation changes (regulation button, back check, bridle wire, etc.). The capstan was proper. When its action appeared to be regulated exactly as those around it, the hammer would rebound against the rest rail. The only way I could get it to behave somewhat properly was to move the back check about a quarter inch further forward than all the other back checks. Then it would not get stuck, but repetition suffered some. I even replaced the jack spring, thinking that was weak, but it made no difference. What have I possibly missed here? Arlie Rauch=
