Louize,

In addition to some of the other advice you've received, I'd suggest
preserving the engine and then *not* turning it over at all until you're
ready to bring your Westy back to life.
Here<http://www.lycoming.textron.com/support/publications/maintenancePublications/serviceLetters/SL180B.pdf>are
some preservation guidelines for an aircraft engine, which you might
wish to adapt.

Perhaps consider some type of oil spray like Krown rust proofing (Canada) or
the equivalent.

Use a fuel stabilizer, or better yet,  just let one of us baby your Westy
for you!
