My wall clock was running and keeping good time. Don't know what kind it only says Korea on the face. It all of a sudden started losing time. I tried to shorten pendulum, that didn't help. I checked beat and it was off. I adjusted beat by moving bottom of clock and now it is in beat and running on time again but it is visible not level. Why?
