Your clock's striking don't sound right.
Chances are, the hammer that strikes the gong (or bell, or rod) is affixed to a flexible shaft, usually brass, sometimes spring steel. When at rest, the hammer should be just a short distance, probably around 1/16", from the gong. If the hammer is resting on it, the sound will be buzzy or it will simply decay very quickly. If the hammer is too far away, the gong may sound only sporadically or not at all. You can usually bend the hammer shaft to position the hammer head the right distance away from the gong.
If there's another buzzing problem, make sure the gong is securely affixed to the case, and check the front glass and any door latches for possible buzzing sources.
