When I finished my car I had rebuilt the engine first and stored it in a bag for 10 years. I basically did exactly what Woodchuck said and it worked great. I’ll also add if it hasn’t been said. It’s a good idea to replace the mechanical fuel pump if it’s been sitting on there just cause that’s a long time for the diaphragm to sit dry.

Not just the fuel pump, but the carburetor's accelerator pump diaphragm and other gaskets. Fill the carb with new gas as suggested and let it sit for a while, or at a minimum don't pump the pedal as that might result in a torn accelerator pump diaphragm.
