Petrof Sticking Keys

I have been called out to service many sticking "keys," as the customer said, 
and found that in probably 50% of the occurrences, it was not the key at all, 
but negative lost-motion(hammer butts sitting on jacks) that caused the 
problem, particularly in newer pianos.  Make sure you check to see that all 
of the jacks can get back into place before you squeeze keys!
