Today we are selling a used Lucas 12° auto advance unit. This auto advance unit has very nice lobes with very minimal play on the shaft. It appears that the auto advance unit was not used very much - very hard to find in this shape. Springs are strong and retract the weights well.
You can use advance unit on any Triumph 650 or 750 twin from 1968-1978 with standard ignition (non-ET) in conjunction with the Lucas 6CA or 10CA points plate. Replaces Triumph and Lucas part number - 54419340 / 99-0771. I would personally use this Lucas auto advance unit "as-is" - needs nothing.
Remember, all parts are used and may have some marks, nicks, etc from everyday use - sold "as-is" no returns.
