I would agree with what some are saying with checking the basics first or have someone knowledgeable help you. Check that the throttle is actually getting pulled all the way open, make sure the choke isn't staying on or the secondaries being otherwise prevented from opening or opening all the way, and check your timing situation.

This is actually a good point. I recently had a deal where my air cleaner was interfering with choke linkage on a quadrajet. Made it run terribly. Make sure your throttle is opening all the way when the fun pedal goes all the way down and make sure your choke isn’t hanging closed.

As far as the timing goes, that’s something you could verify pretty easy. There isn’t much to it. Buy a cheap timing light, plug off the vacuum advance temporarily and just see where you are at. It’s not that the shop doesn’t know how to do it, but if they weren’t given specific instructions on where to set it who knows what they did.
