I am not sure where to post this, since it is not exactly a repair, but I assume whatever steps I need to take would also need to be done after a good disassembly and cleaning, so here it goes. Besides, I have enjoyed the discussions with the people on the repair board.
I have a 1908 Junghans box clock with a count wheel movement (my first experience with a count wheel). I know it needs a good cleaning, but I wanted to see if it works at all to begin with. When I first tested it, it was counting somewhere around 51 o'clock, and I figured I would look at it the next day. But after the next day it was behaving reasonably but seemed to be off by 2 hours (struck 8 times at 10 o'clock). So I wanted to test it a bit more, but when I moved the minute hand to 10:30 is struck 9 times, and at the 11 o'clock position is struck 10 times. There is a pull rod on the right side (left in the picture) that seems to advance the count in some way. My questions are:
1. Does this behavior indicate a serious problem, or is this normal?
2. Assuming no malfunction, Is there a recommended procedure for setting the strike?
3. If it behaves this strangely from the start, what problems should I anticipate after I clean and reassemble?
