I parked my truck in the side yard and it hasn't been started in about 6 years. I'm looking for things I need to do to do it "properly"...whatever that means. It's a got a 350. I'm thinking new oil and filter, new plugs, squirting oil in each cylinder. Priming the oil system is what I thinking once the new oil gets put in. I have a Tavia primer. I read about using an air ratchet to turn the priming tool........... is the impact from the air ratchet a good idea, or can it do damage to the pump or break the oil pump drive shaft? I'd of course install a new fuel filter and maybe taking the top off the carb (Q-Jet) to make sure it's clean inside with no flaky residue. Gas tank was almost totally out of fuel when it was parked. (6 years ago) I'm thinking of adding 5 gallons of gas then putting a rubber fuel line into a clean bucked while turning the engine over so I can observe what gets pumped out......... clean or globs and crud. That will tell me if I need to go deeper on the tank subject..and I don't want to. I'd rather add a larger filter. Coolant still looks nice greeninsh yellow, so I'm not gonna mess with that now. New oil/filter Prime engine New plugs (Cap and rotor are in excellent condition) Clean carb and replace filter What else? Belts can hoses can be replaced later.
