I am trying to find a service manual, advise or anything that could help me put back to factory setting the idling adjust spring. I make the mistake of mess with it and now I am not sure how to find out proper adjustment. Nothing on manual shows how to do this, at least not in the manual that I have. Is the number 6 and 5 on the picture attached. Right now I get a good amount of white smoke. I have done every step clean fuel, new injectors, rebuilt injection pump, not coolant loss.

Any idea would be appreciated.

The idle adjustment is not causing it to blow white smoke.

Did you rebuild the engine?
