You now know the correct orientation of the spinner to backplate,
Now let me pass on a habit my instructor taught me.
Tighten your prop so that when you turn turn the prop counter clockwise when facing the front of your plane (same direction your starter turns it) it will hit compression with the prop horizontal to the ground.
The reason is simple enough, if/when you deadstick the prop will turn in the wind until it reaches the compression stroke of of the engine. If the prop is sitting horizontal when this happens it is less likely to strike the ground in a less than perfect landing.
