I put Sta-bil fuel stabilizer in the tank of our old '67 Camaro RS, and then ran it long enough to get the stabilizer into the carb. After 5 or 6 years of storage without being started, we moved it to my FIL's house on a flatbed.
He put a new battery in it out in the driveway, but didn't have anyone to help him push it in the garage. Figuring he had nothing to lose, he poured a little gas in the carb, and turned the key. It started right up, and he drove it into the garage.
I recommend Sta-bil.
