    1979 speed control problem

    I have a 1979 in the shop, that the speed control does not work. The shop manual does not even mention the speed control. Is there a manual I can purchase to take me through the operation, and troubleshooting of this unit? Thanks, Mark

    If the cables are OK the speed control unit needs replaced. Many of them have failed.

      Check the vacuum which is supplied to the unit.

        I assume I should have engine vacuum at unit when idling? What does the servo do, and the transducer? I would like to know the sequence of operation. I was looking in Zip's catalog, and they list a transducer and a servo. Mark
