TR4 inertia starter motor has bent armature

[barrytr4]

Hi Mates 

My TR4 has inertia Starter that has bent the armature , it was working fine then sort of siezed up , the engine was cold, the shaft had bent a few degrees, at the same time? when I stripped it I saw one of the brush leads had gone to earth and had burnt the wire out, is it worth trying  to straighten it?  while I'm here the engine seems hard to turn by hand when hot--not too bad when cold-----Barry
