Awwww bummer! Just promise no alias if you do sneak an occasional game in, so we can say hi!
For now, youre gonna need an engine preservation, or "pickleing."
I'll help.
Step one: drain oil and replace with half mineral oil, half cosmoline. Run engine at idle for five minutes.
Step two: pull your spark plugs and spray knox rust solution liberaly on the cylinder walls. Pull the prop through by hand for four complete revolutions. Replace spark plugs with fresh dessicant plugs (do not eat.)
Step three: place as large a bag of dessicant as possible in the induction and exhaust systems.
Step four, put a sign on the prob that says "do not turn, engine preserved." And put a similar sign in the cockpit over the magneto switch.
I'll be checking your dessicant plugs monthly til you get back. Just give me an hour notice before you need to go up again and I'll have her waiting ready on the ramp for you, ok bud?
