Your chime notes don't sound right.
Chances are, the hammers that strike the chime rods are affixed to flexible shafts, usually brass, sometimes spring steel. When at rest, the hammers should be just a short distance, probably around 1/16", from the chime rods. If the hammers are resting on the chime rods, the sound will be buzzy or it will simply decay very quickly. If the hammers are too far away, the note may sound only sproradically or not at all. You can bend the hammer shafts to position the hammer heads the right distance away from the rods.
If there's still a sound problem, it might be that the "music box" drum is not positioned correctly (typically on triple-chime clocks). A qualified repairman should be able to help with this.
