Need directions for Adjusting CO tower mixture

I have gotten a rebuild completed on my fuel distributor for my 1986 Mercedes 190E 2.3-16v. It was leaking and not allowing the car to idle correctly. I am ready to reinstall it with a new fuel filter and a new EHA Unit. Can anyone direct me or explain to me how to adjust the CO / oxygen mixture tower so I can correct the adjustments that were done to compensate for the bad fuel distributor? I had done this once before and had instructions but it has been too long now and I can find the papers that explained it.
Thanks.

rebuilt fuel distributor

The company that rebuilt the fuel distributor told me that the diaphram gasket that is inside the distributor had worn out and cracked causing a fuel leak and not allowing the correct pressure at low rpm. What ever the problem, the rebuild was done and it idles correctly now. Sorry I dont know more about it.

Sounds good. About two months ago a guy was selling rebuild kits for Mercedes Bosch fuel distributors. He had several model specific kits for about $80. You might check there first. He also had a link for complete instructions on the task. I read them and decided I didn't want to tackle it myself. It looked very tedious and easy to mess up.
