How should the clock be in its final position?
Now your clocks all running well and together, if it stops at all check the beat tick and tock. Be sure its in a good beat. If it runs for like 3-4 days and stops, like when the weights get down to the bob area do this. You fix this by moving the top of the clock case away from the wall. Its like the whole case is swinging with the movement and pendulum in a way. And when its up against the wall on the top side then it will stop when the weights and bob are the same height.
