Engine Rotation Terminology
Engine rotation direction is determined by observing Flywheel rotation from the flywheel end of the engine looking forward to the pulley end of the engine.

Note: Propeller rotation is not necessarily the same as engine rotation. Do not rely on propeller rotation in determining engine rotation.
