I don't agree with the advice already posted.
On both a 4 and 2 stroke I flick the spinner backwards against compression which is CWclockwise when looking at the front of the engine where you would be to start it.
I also use a chicken stick on the prop to flick them backwardsCW against compression .
Sometimes I also use the chicken stick to flip the prop thru compression CCW-counter clockwise only on a 2 stroke.
Clear as mud but you should get the picture.
