ressurecting a sleeping beast..need help/advice

its sat with the carb off, but the engine is installed in the car with the hood shut. It is stored outside, in rain/snow...Im worried about the moisture in the air though...

if I were to put a carb on it, I would have a can or jar of gas in the engine bay to run off of untill I can drop and flush the tank...

next question...anyone have a cheap carb and alternator they would otherwise throw away???
