The Main Blades should turn CLOCKwise and the tail blades turn toward the back when facing the tail. The motor and tail are the only thing that suppose to be c-clockwise. If the tail it turning clockwise you may still have belt twisted. Sound like you may not have a big problem after all. Now put the blades on correctly. Paddles and tail rotors also. The motor is still rich. turn the low end screw clockwise to lean out the low and mide range Do it a little at a time. all heli motors run rich to keep cool and will have a lot of smoke coming out the pipe and that is normal.

As a note most model helis have a clockwise main blade rotation and most full size (real heli ) have a c-clockwise rotation. There are always a few exceptions.
