Be careful, from the driver's position the engine does turn counterclockwise.
So you better write: "I will not turn the engine in the wrong direction". I'm also glad you calling it an engine, not a motor.
I had a '59 180D, a push rod engine, and it had a flapper valve in the intake air horn to prevent the engine from running backwards if roll started in reverse. The engine would intake thru the exhaust pipe and blow exhause thru the air cleaner. Only damage was the oil pump would run wrong way so there was no lubrication oil getting to the to the engine. So the flapper valve in the intake stream would close and not allow the engine to run backwards.
