One question: what would be the better way to shut down for easy restart?
Mags or mixture? -Bill Wade

Bill, I would use mixture.  Using the mags allows gas to wash down the cylinders, which in my opinion is not a good thing.  Additionally by just pushing the red knob in will bring the engine back to life without any worry of fouled spark plugs.  Personally, I would slowly push the red knob in.  How slowly would depend on whether or not I was about to land at a desirable spot.
