The best "restoration" for the rubber bits is "replacement". Some have reported modest levels of success by soaking in Wintergreen oil, but I have not heard if it lasts or not. New items will last another 20 years or so.
It might seem to make sense to use gasoline as a solvent to remove all the crud that was placed there by gasoline, but I don't think it would be a wise move. Your state leaders might have legislated the preferred chemicals off the shelf, but see if you have Berryman's Carb Cleaner Dip or Gunk Carb Cleaner Dip. Both come in a one-gallon can, both have about 3 quarts of liquid inside. Don't follow the directions.
They likely say to immerse the parts for 15-30 minutes. Most of us feel that those directions were probably written MANY years ago, when the chemicals in the can could actually do the job in that amountn ot time. We now recommend immersing the parts for 15-30 HOURS. Yep, basically a whole day.
There is a basket in the can to hold the parts and makes it easier to lift them out. If you ignore the basket, you can stack two carb bodies on their sides. Two bodies on the first day, the other two bodies the second day, then all the jets and float bowls on the third day. Float bowls??? Yes. They have the passages that feed the "choke" system and might be clogged.
