Sft{Mr Swift}/Mr Break. re Starter Switch This confirms conversation with you respecting the weakness of the duralumin arm carrying the copper brush on the new starter switch, and that you will see if it is possible to make some simple modification such as the addition of turned up edges to stiffen the arm, so that it will not take a permanent set in use.
