87 300d bad cruise actuator

I have narrowed the cause of my non-functioning cruise control to the actuator.
I've read that they can be repairable. But I can't find the specifics about it.
It seems the potentiometer part of it isn't working, so to my mind it sounds like posibly a good cleaning maybe will do the trick. I don't know.
I haven't taken it off the car yet.
Thanks in advance.

1991 Mercedes 300D Turbo Diesel - HELP!

Please help me. I have a 1991 MB 300D 2.5L Turbo Diesel. When I attempt to start the car, it has trouble staying in idle. I have to pump the gas pedal 4-5 times in oder to get the engine to run and have the gas pedal down at least half way to keep the engine running. As the engine runs, there is a cloud of white smoke coming from the exhaust. There is no blow-by, however when I uncap the radiator cap, a froth of bubbles rise after 5 minutes or so of running.
