gear and main-gear. After that moderately tighten the four M3x12 screws, recheck the backlash. Use the M4x35
screw to lock clutch bearing block.
Alternatively, you can insert a piece of paper or plastic sheet between the two gears, press the gears together,
then lock the engine mount nuts, pull out the paper, then check the gears backlash again. Using this method the
main gear and pinion gear have to be parallel.
