Greetings Sir, From your description it sounds as if you have tight action centre pins. If you can remove a hammer butt assembly, you can check to see if you have 4 to 5 swings. If not the best solution is to shrink the bushings with 50% alcohol and water. This should only be done by a skilled technician, who will be able to confirm the cause of the problem. Too much friction in the key bushing will also cause a similar fault. With out seeing the piano, it is difficult to give much more advice. Get a second opinion from another technician. Preferably some one with some rebuilding or major repair experience. DO NOT use oil on a piano.
