John what you are showing will happen anyways without the door being closed if the snail wasnt put back on properly in the first place. You have to time the clock. I have experienced the same thing that you are discussing with the door open on a clock. Move the snail one gear tooth and it fixes it.
I latch the door and it doesn’t make noise but when I open it the bird comes out and it doesn’t make a noise until the hour or half hour. The problem is that the times it cuckoos is wrong now. Is there a way to get it to stay accurate to the time
I have a cuckoo clock the instructions were to set it at 5 or something have lost instructions and now time is wrong and won’t automatically go off at night?
