You can't fly the plane without it.
If the plane has sat, unless you're going to get it for less than what a replacement engine costs, I'd pass. Every piece of rubber is going to need to go over (tires, gascolators, hoses). You're at least going to want to take a look in the cylinders to see if they're rusted.
