Forget about the auto advance bit by loctiting the cam to the main shaft and use manual advance /retard on the steering column. Something to tinker with when you are driving! I have read somewhere in an A7 book that one variety of DK 4 cam is a superior shape. You can rebush the shaft as they are (were?) available from at least one of the cherished suppliers.
