Gear adjustment : You need to take some paper (note paper is ideal), and cut a piece off, approximately 1/2” x 3”. Then you insert that paper between the pinion and spur gears, and put around 1 lb of force on the motor, making sure that the gear's teeth mesh properly. After tightening down the motor mount screws (refer to point #1) and removing the paper, you should be ready to run all day!
