As to the start switch just take it apart and clean it. The old switch have better metal, many of the "new" are made with recycled brass with impurities.

Agreed with taking the switch apart. Most of the time it's arcing/burning on the contacts causing bumps that is the problem. A little sandpaper and off you go. Bren carriers (if original) have close to 15' of 0 gauge cable going from the battery to the dash starter switch to the starter (what, they didn't know about relays?) so clean, soldered connections are critical.
