Like they say in the movies; "If you want something done right, better do it yourself".
Get books on your carbies. Get air/fuel ratio gauge, (make sure it's a multiwire one). Get some type of vacuum gauge for setting synchronisation.
Many carbies (regardless of make) are internally out of tune and can _only_ be adjusted back right again by a complete disassembly. That does consist of realigning the butterflies and so forth, so I'm not on about taking jets out for inspection and screwing them back in again seconds later.
Many clever articles are in the net. Even instructions for (motorcycle people) making your own 4-pylon display manometer gauge for vacuum reading. (Naturally works for us car people as well.) Only 2-pylon gauge needed for cars, just check throttles within carb body to be okay and then connect either pylon to display their own carbie body. This will work great on Weber/Dellorto twins.
After two intensive months of self education, you're better tuner than below average dyno guy.
