Weber WEBWK551-36S base settings?

I have a weber WEBWK551-36S and when I try to adjust it I can turn in the air fuel mix screws with no effect what so ever. I have tried so much I cannot seem to get it back to normal. Can someone tell me what the base settings are for the air fuel mix screws , the fast idle and idle speed screws. I want to start from where they were when it first came out of the box.

The Instructions just go over how to make adjustments NOT what the carb is set at out of the box. As stated in my post. I have made so many adjust ments I feel as if I need to go back to square one. In order to do this I need to get the carb back to the "out of the box" settings.

Which is written clearly in the directions.

I don't know what the baseline settings are for the carb you have, but they are usually something like.....

Idle speed screw set at 1/2-3/4 turns in after contact.

Mixture screw set at 3/4-1 turns out after bottoming it out.
