The mechanics and engine manufacturers are now saying DO NOT pull the prop through unless you are about to start the engine. People used to think that pulling the prop through once a week (or so) was a good idea since they thought it helped the engine. All it does is wipe the oil off the cylinder walls, so eventually all you have is bare metal scraping against bare metal. Moving the prop a tiny bit each time is o.k. to keep the rings from seizing. The engine manufacturers say "if an engine is not run for more than 30 days it should be preserved with preserving oil and desiccant plugs should be put in the upper spark plug holes in each cylinder." I agree with you though, Percy. She should just start it, make sure she has enough oil pressure, and go fly it.

I try to pull the prop through every time I visit my plane. Don't know what good that does, but it hasn't quit yet. Now that I have retired...I have time to go flying and can keep some hours on it. Get With It! I went up yesterday (high winds) and today (just perfect). Stop agonizing over the oil and Fly It!
