Thank you for your efforts here. Move the pendulum to the far left of center and release. The three weights provide power to the hour strike (left weight), time (center weight), and chime melody (right weight). Re-set the minute hand to the exact, correct time. Right now the chimes are running 4 hours ahead of real time. When it is 12:00 instead of 12 chimes it does 10 chimes. Thanks in advance for your help.
