How do you adjust the air/fuel

How do you adjust the air/fuel mixture on Edelbrock 1409's. Do you really need a vacuum gauge? If so where do you connect it? Thanks!

"A vacuum gage helps a lot IF you can find a place to plug it into. DON'T use the PCV hose or you'll be way off.

The idle mixture screws adjust the mixture. If you've never done it before, get someone who has. Tricky.
