I always pour transmission fluid in the oil the night before. Turn the crank with a wrench a bit before you start it. Give it some fresh fuel and let er run for a bit. Sea foam the intake, add the rest to your gas, then do as TripleJ said. I had a Chevy truck set in a field for at least 7 years and now I drive it a few times a week to haul horses/hay/building materials.
