Its another cuckoo clock problem. The clock works, keeps time, ticks away nicely but I cannot set the precise time with the minute hand. It can't be moved forward or back, yet when the clock is ticking, it works fine. Any hints on where to start to look for the problem. Everything else works on the clock. This is a 1950s Hubert Herr large cuckoo clock, 17 inches top to bottom. Any suggestions ?
