Narrative:

Engine starter would only crank engine to top of compression, so I decided to hand-propeller. My wife was in passenger (right) seat. Engine started immediately and I moved out of the way. My wife panicked because she couldn't see me, reached over to shut off key, and bumped the throttle, aircraft moved. I climbed in cabin, idled engine and returned to parking area. Aircraft traveled about 100 yards over parking area into grass. No damage/injuries. Train my wife!
