    They should be up front - one on either side, sort of hidden in little grooves. They probably have limiter caps on them (easy to remove) and possibly require a special tool to work them - kind of a oval shaped deal. Mine is a Mac CAT5525 - comes with all the ends for adjustment of all GM carbs, $14 off the truck.

    The only mix screws are the Idle mix screws. They are on the front of the carb near the bottom

    That's the ones!! You can use needlenoses if they clear the intake - I've got a Performer intake, and there's about zero room to get anything in there - the adjuster tool is a pretty tight fit. Pep Girls and AutoZone should have a screwdriver type version of it, that should work as well.

    You can also make a took to do this adjustment. You can get some small copper tubing and flatten it out a little on the end or use some plastic or even wood dowel. Just make sure that it will fit in the holes. To make the tool easy to use, keep the part that fits on the screw tops short. Then link them to a pair of screwdrivers with some vacuum hose or fuel, making a short universal joint. Then you can adjust both screws together just by twisting the screwdriver handles. It worked for me.
