Cuckoo music governor is binding on something

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.

Hi, Cuckoo, welcome to the message board. It is important that the new governor matches the rest of the music movement. Count the teeth on the pinion gear on the old governor, and compare with the new one. If it is new, it shouldn't have needed any adjusting, other than fitting the mounting holes to match the movement.

You say the holes were worn; does that mean that you fitted a new fly with larger pivots and broached the holes out?
Would it have been better to bush them? Is there anything else wrong with the fly? The holes do not often wear, IMO. Very little power there.

These things only just about manage to work when everything is OK - driving a worm from a wheel is not the best sort of gearing.

Cuckoo - as you've already verified, it is cheaper (time wise) to just buy a new music movement. If you enjoy banging your head though, you've found the perfect way to encourage it :)
If you can't find the correct song, you might be able to change out the harp or the wheel - or even both easier than trying to fix the governer.

Thanks, Harold, you were right. The new governor was too large for the movement. I finally had some time to play with this clock again, and I gave the movement a better cleaning. I put it all back together and fiddled with the way the governor fits to the music box itself, and it started working again. At any rate, after lots of time messing with this clock, it's working the way I want it to.
