I'm working on cleaning and repairing a musical cuckoo clock and I seem to be banging my head with the governor. The old governor had worn pivot holes and was binding because the gears had too much play. I got a replacement governor, and installed, everything works fine except that if the butterfly fan is in place, it won't run. If I take the fan out, everything moves very nicely. I tried adjusting the top pivot - looser, tighter, in, out - nothing works. It just sticks and won't allow the movement to play. Any ideas on what to do here? I'm at the end of my ability here.
