Are you attempting a rebuild on the carb or the whole motor? If you're unsure of how to adjust the idle mixture on a Q-Jet you might as well forget about rebuilding it and just get you an Edelbrock.
I know some Q-Jets had small caps put over the mixture adjustment screws to prevent people from tinkering with them. You can knock them out and get to the screws though. I had an emissions inspector try to fail a car once because the plugs were missing. I had to go to his supervisor and reason with him to get past it.
