Should I try to start it

Agree with the above (318WR), but I don't know if I personally would be able to resist trying to fire it...
Clean it up. If the engine is loose, squirt a little oil in the cylinders and spin it over by hand. Pop some fresh plugs in there. If a points dist., clean the points and reset the gap. Fresh oil (just use cheap stuff if you're tearing it down anyways) and prime the system. Make sure coolant is good... Run a fuel line from a can so it gets fresh gas. Static time the dist. and fire that puppy up.
