Lucky, i got it right up the nose! That was some bullshit right there....:mad:
You can turn the housing up into the spiral gear and feel it touch, then back it down to closest numbers at 6:00 tally mark. The smaller tooth count are smaller diameter geats so figure rotation direction out.
Edit: the spiral gear is on top (upper left for optics ) so you can see where the gear is by the offset of the housing. start with threads at bottom largest numbers at 3:00 and turn it clockwise to raise gear into spiral output shaft .
