I know this is a basic question and I should know but I'm confused. I figure I'm running the engine in the correct direction as I am getting thrust behind the prop. If it was running in the wrong direction, it would be pushing air out the front of the prop, correct?

Also, which direction should I prime an engine before starting it, when facing the prop, and which direction should the engine run in from the same location, facing the front of the engine? My starter is turning the prop counter clockwise when facing the front of the engine.

Last, what can happen to an engine running in the wrong direction for a short and also for a long period of time?

Thanks in advance.
