CORRECTION: Clock at had to be lifted slightly on left side. I fixed the clock. I turn leader slightly to left side. Now it runs e without lifting the clock. SEE PICTURE AND VIDEO BELOW. I DID TESTED FOR 5 DAYS BEFORE. BUT AFTER SITTING A WHILE CLOCK HAS TO BE LIFTED. THIS IS EASY TO FIX. FROM BACK, WE RAISED THE RIGHT SIDE. SO, TURN THE PENDULUM LEADER TO RIGHT. I WILL TRY TO DO THIS. I WILL DO THIS WHEN CLOCK STOPS. STARTED 4/9/24 AT 2:41PM. WILL UPDATE WHEN IT STOPS. Clock is still running. Today is 4/16/24 at 3:00PM. Thus far it has been running for over 7 days. Clock Stopped 4/17/24 at 10:55AM. Clock ran 7 days 21 hours and14 minutes. NOT BAD RAN ALMOST THE 8 Days THIS CLOCK IS DESIGNED TO RUN. I GAVE PENDULUM A NUDGE TO SEE HOW LONGER THE CLOCK WILL RUN. I GAVE NO EXTRA WIND. ITS 4/17/24 AT 1:18PM. WILL UPDAT WHEN IT STOPS. I DO THIS TO ALL CLOCKS I SELL. MOST RUN 1 TO 4 MINUTES ONLY. THIS ONE IS ALREADY NUMMING OVER 10 HOURS SO FAR. Clock stopped 4/18/24 at 7:37AM. It ran an extra 18 hours plus 19mminutes.
