It sounds like a bad/dry joint somwhere on the arm, normally they do this when they've got too hot and thrown the solder off the joint between the windings and the comm. There's not a lot you can do about it usually, you just need to replace the arm
To check for it I would measure the electrical resistance between each comm segment with a meter, that should give you some idea where the problem is on the armature.
