Hello My name is Ian ~ I am not on the site constantly so please be patient whilst waiting for responses to you queries ~ only two things it can be if you rebuilt it correctly, a faulty armature or poor quality brushes, did you check that the commutator wasn't rough and aligned and that the brushes were able to slide in there holders? From what you have said I would suspect one or the other. Ian
