If the needle yoke is stopping halfway back I would suspect the whole knotter isn't completing its cycle either. If this is the case then the problem is likely in the knotter clutch, (broken spring, worn or loose roller etc.). If the knotters complete their full rotation and the fingers stop in the middle there is a woodruff key inbetween the shaft and bellcrank that could be sheared but it is not very likely. It is IMPERATIVE that when you check anything these are in order first: 1. Check plunger to needle timing, inside the front cover there are marks that the plunger arm will center between at 12 o'clock. With the plunger there there are punch marks on each of the two cast parts of the knotter clutch, they should either align or be within about an 1/8" approx. IF THEY DO NOT LINE UP find out why. In your case I'd bet that pulling on the needle yoke rod as described in my previous post would put it back in time. Then after cycling it does it again, I'd suspect the knotter clutch. EDIT P.S. I forgot to add If you only pull the needle yoke back til it locks and don't reset the knotter shaft by pulling the rod back this problem will persist until you do.
