Mercedes Benz repair: Idling speed, air mixture, auto mercedes

Question
My car is a Mercedes Benz Model 126, 280SE Petrol Saloon. Can you tell me what is the idling speed and where is the idling adjusting screw. Also how much do I adjust the air mixture screw?

Answer
What year model?
The air mixture screw should not need adjustment; unless you have other problems.
Many people seek to adjust the air mixture screw, make one mistake and you will be buying a new or rebuilt Fuel Distributor = roughly $2000.00 USD.
Best advice:
Take the car to a good MB technician.
The cost will be cheaper than a patch that makes the real issue worse.
