Wow! 1976? That's beyond a "Classic Wing", that's a "Vintage Wing!" Good luck with your project. There are some very knowledgeable people here willing and able to help. Should be fun to see and hear about its resurrection.
The first thing I do with older bikes that have not run for quite awhile is to soak the rings with 2-cycle oil, about an ounce per cylinder, through the plug holes; new oil and filter, too. After a few days of soaking, give the starter a short bump, and repeat each day while you're working on the second thing, rebuilding the carbs. Just pulling the carb bowls off will tell you if it's absolutely necessary, but it's always wise to do.
Welcome from Mississippi. Good luck with your project. I'm not much help getting those older bikes running but I sure love it when someone gets them back on the road. Fixing up an old bike is in my retirement plans but that's a little bit in the future.
