Try flipping the prop backwards to start it. Don't push it all the way through the compression stroke backwards so it starts backwards. It is the same as your current method but the reverse kick will start it forward.

If you engine does start backwards it will idle for a little while but will die if you advance the throttle. I have been able to get the engine to kick back to forward from reverse by tapping the nose of the spinner. Be very careful though. It hurts to get bit by a prop and it could cause serious damage to yourself.
