I rebuild an Ansonia A 26 tampour mantle movement. It has a rack and gathering pallet. On the half hour, the warning wheel is activated, the gathering pallet is turned. When the warning is released, only one hammer hits and the other is left half way up when it stops. I turn the hand to the top of the hour, the warning is activated, the warning is released and only one hammer hits. The Gathering pallet is turned about 1/4 turn and is caught on the teeth of the rack. I move the hands again, the gathering pallet turns 1/4 turn. I move the hands again, warning is activated, then released and the rack falls as it should. Then its back to square one again. I have moved the warning wheel a number of times but it still does the same thing. WHAT AM I MISSING? Any suggestions?
