You need to find the number on your Q-jet. It will be on the drivers side toward the rear where the long screws go through holding the top on. its a 7 or 8 didget number.
If you go back to the factory setting, you should be pretty close. Try a softer spring under the primary metering rod holder. Vacuum is what pulls them out of the jet and a stronger spring will get them out quicker. A softer spring will keep them in longer and improve your fuel mileage.
I have a ton of paper work on Q-jets, a couple of books, and years of working on them. Cliff is a good friend of mine and my dad and has been over to the house a few times. He is the best there is for performace tuning a Q-jet.
