don't count it out. I was given a 72 dodge truck back in the mid 90s that had been sitting in the weather for over 20 years. it had 18k original mile on it. the body was falling off with rust. I put a battery in it drained out the bad gas and it fired with no problems and even drove it. still sounded like a brand new motor.
Going to be a little tougher than that if theres been water and OK mud getting in the cylinder bores. Be stuck fast like an old tractor thats been sitting out in the weather with rain water running down the exhaust pipe for years.
