I am working on a western union self winding clock and have cleaned and it runs great but I cannot get the self winding part to work correctly. I have done all of the adjustments from the repair articles that I have, but the armature will not vibrate correctly to wind the mainspring. I have been trying to adjust the upper spring limit arm as the article suggest, but how is this done? The spring is on a brass base that is screwed to the clock so how is this spring adjusted to just touch the armature. Is there something else am missing. I thought I had it fixed at one point but now it will work for a few seconds and then hangs up. thanks for your help.
