DK4 Automatic Advance

[Bob Culver]

Austin company post war books give the late static timing as a conservative tdc. Timing must be judged by perfromance not noise. On my RP when stock moving the manual timing over a vast range had a marked effect on noise but the speed remained unchanged; 50 mph.
Whether auto distibutors have the appropiate springs is anyones guess. Those with time to spare can arrange an old motor mower or choke control as a manual override . Give driver something to play with when grindinging up hills.
