Hi everyone - I just picked up this cuckoo clock at a yard sale for $40.00. The owner said that it had been refurbished fairly recently and it seems to work fairly well...except that it seems to be skipping a gear while ticking? I don’t know squat about cuckoo clocks. You should have seen my trying to get the chain back on one of the gears lol. Is there a way to repair a skipping gear? Or do I need to take it in for service? Also, the clock struck 12:30 and the cuckoo chimed 5 times.... ? How the heck to do I fix that?! thanks!
