<<snip>> ... but, doing this pushes the nose left (when facing the plane)... <<snip>>
The right side of the plane is the side where the right turn signal would be, if it had one. If you wanted to add right thrust, that's what you've done.
Isn't that backwards to counter balancing the prop inertia?
Eh? Right thrust counterracts the P-factor.
You'll know if you need the P-factor correction when you make a vertical climb. If yaws to the left, you need more right thrust. If it yaws to the right, you have too much.
Good luck,
