Demon NO Go

You're getting there Cheryl. Keep your chin up. the higher vacuum means its using the extra fuel. It was lean, and might still be. You want to balance the highest vacuum reading with the idle speed you want. Also, how is the float setting? If you have to open the mixture screws that far, it sounds like the float level might be too low. It should be high enough to dribble out the hole at idle. Is the car an automatic or stick? If it's automatic and
you can keep the vacuum at 9 or 10" in gear (that is about what I would expect to see with that cam...) then you can up the power valve a little, it will like it better.
