Help Music Box Drum issues- Cuckoo

[Willowind]

I am working on this Sch Cuckoo. The trouble is: (1) the weight (275) isn’t enough to completely follow through the duration of the tune, and (2) the displacement of the pause on the drum. There doesn’t seem to be an adjustment to bring it back up to the silent space on the drum.
Helpful advice will be appreciated.

There is more to clock repair than clean, oil and adjust.
Clock movements (and music movements) normally fail due to lack of power due to friction due to long use.
You will find that music movement governor is worn to the point that the friction has overcome the power supplied to the movement. In addition, there probably is wear in the drum arbor, causing additional friction. Clean, oil and adjust will not solve the problem with that music movement.
Music movements can be a challenge even for experienced clock repair people and are many times damaged beyond repair by novice repair people.
If you are unsure of yourself, it may be a good idea to enlist the help of a well qualified, experienced clock repair person.

you can try raising the weight to 320 turn the drum till the lever goes in the hole on side then adjust chain gear on the shaft to when the man would be back inside music box will probaly worn out like Dick said

There's a small plastic gear on the fan that often cracks, making the box unusable. You can get replacement fan assemblies, but they usually require quite a bit of altering to make them work. You might be able to fit a new music box into the case. Cuckoo clocks are usually too costly to have repaired unless a new movement is installed. If your music box is worn out, the movement won't be too far behind.

Without knowing how the music movement operates, you have a slim chance of solving the problem/s with it.

Thank you for the link to Banster’s post. Very informative and helpful. I isolated the problem, and was able to fix it. It’s running properly now.

What was the problem?

What was the problem?

The comb had been adjusted too tight, and was stalling when multiple tines were trying to be played. After careful adjustment, it is working now without stalling.
Thanks for the help.

I just saw this same problem with the comb being adjusted too tightly. The movment itself looks really dirty. It needs to be stripped down and gone over, maybe bushings,
