I have cleaned and re-bushed this Gilbert half- hour strike clock and now with it on the test stand I put it in motion. It runs fine except that when it begins to strike the hour the movement will not stop. the count lever does not drop down into any of the count wheel slots and the locking lever does not drop down into the locking cam. the photos may not help but here they are. Anyone ever had this problem with a Gilbert I have read Conover's book on the Gilbert but it hasn't sunk in what I have done wrong.
