Happy birthday! And I hope you have many more to come!
Yes. Soak those cylinders in ATF. A good tablespoon or two per cylinder. Especially before trying to start an engine that has not run in a while.
Drain the gas and put fresh gas in.
Some carbs have a spring that returns them. I have 2 that do and 2 that do not.
Get an I&T FO-4 shop manual and a owners manual. Both are available from this site. They are very good. Ford N parts from this site are also very good.
Good luck and keep us posted.
