Balancing the torque with tilt is one problem with the Congreve among a litany of others. In my experience, the situation can be improved by changing the ball size. Wilding calls for a 7/16 in. diameter but I found that I couldn't get the clock to perform until I used a smaller ball (13/32). Any ball bearing supplier can provide individual balls in any size as these are manufactured to great precision. The unfortunate thing is that they are not usually available singly but packages of 10 or twenty are reasonably priced. The choice is between having a ball that is too heavy to lift and too light to release the detent. Good luck.
