350SDL rough idle
Sounds like a reasonable test and it is one that we have made - compression was OK. This was also pretty much eliminated as a cause because when it starts, is runs smoothly for a few seconds - after that is when is goes to running rough for a period of a couple of minutes. Is there any pump adjustment? Noticed that there is an adjustable bolt on the back of the pump - just above the electrical connection. What does the electrical connection control? When it is running rough it changes slightly when I disconnet the electrical plug.
