To speed up the clock tighten the nut turn it toward your right.
The movement that s in the clock also does not appear to be a very strung runner rather weak pendulum swing.
A clock that runs quickly still works fine.
Locate the adjustable weight or screw mechanism near the pendulum arm.
Use the following rules to adjust the pendulum nut.
Adjust the pendulum up or down.

Pendulum bob with rate adjustment french time and strike.

If the clock is running slow turn the pendulum nut clockwise to increase the rate.
Fixing a clock that runs too fast can be as easy as turning a screw.
