Carter 2BBL carb- I am stuck

put a guage on it and adjust to the highest reading

It reads the same no matter where I turn the screws.

Turn them all the way in and back out about 1.5 turns.
How does it run other wise?

As I stated, I was at 2 1/2 to 3 turns. I will go out and try 1 1/2 turns when I am done here
