How do I fix the Strike Hammers that are stuck in the up position?

The hammer(s) on this one are controlled by a star cam in the center of the strike gear train. When the gear train runs, the star cam turns, and lifts the hammers by the stainless rod coming going down the back of the movement to the hammers The star cam does turn with some force independent of the gear train. So the solution to this is to remove the movement, put your finger on the top of the gear train or fly / fan, and then use a flat head screwdriver on one of the star cam teeth as to push it up some. In this way the star cam will turn without the gear train spinning. So when the star cam is moved alittle on its arbor, the hammer lifting wires will be in the center of the star cam teeth at rest, not on one of the teeth at rest.
