AAAARRRRGGGGG!!!!!~!

Since you are a newbie let's get your education back on track.

Right thrust compensates for P-factor, NOT TORQUE

Torque is a rolling moment that acts about the centerline of the aircraft. Bending the engine off in an odd angle has no effect on the amount of torque produced by the engine. P-factor (which is a difference in thrust between the downward and up ward moving propeller blades caused by relative velocity and angle of attack) causes the plane to yaw left.

In the original post there is the minor possibility that you have too much down thrust, which can reverse the effects of P-factor at low angles of attack.
