I agree with John's advice. If the engine sat for long, especially in a humid condition, the chances are excellent that the rings have rusted to the cylinder walls. Lots of snake oil (PB Blaster would be my choice), patience, and gentle persuasion should do the trick. If permanent antifreeze got into the combustion chamber (for example, from a blow head gasket or crack) then the chances are excellent that a piston has corroded, swollen, and will most likely have to be destroyed to remove it - I hope that's not the case, it can be a bear to remove especially if it's midway or lower in the bore.
