Good news Clive, but that's interesting as you'd think the resistance of any brushes would be negligible. I know yours were cracked (weird) but surely they were still passing current?
the one was split wider than normal and not moving well in the carrier and the other was split in half where it meets the commutator. The brushes are actually wider than each sector on the commutator so I think they should create current in more than one winding on the armature. That is my guess but it now turns over like the starter on a proper motorbike!

Wow, that's a pretty elementary mistake. Glad it's sorted anyway. I guess you don't need a replacement now?
