I have a wind up 31 day regulator clock, it tends to run slow. On the bottom of the pendulum is a knob, I forgot which way to turn it to speed up the clock, clockwise or counter clockwise? Thank you!!!!

The frequency of the motion is dependent on the length of the pendulum. So, in order to speed it up you would need to turn the knob in the direction to shorten the pendulum - I would assume that would be clockwise.

Thank you, I will go try it!
