I am following the instructions on here:
And they say:
"Sight gap between inner chain plate and inner cage plate. Only a small gap should be visible, about 1/16″ or 1mm, about the thickness of a dime."
"If the gap appears larger than 1mm at its widest point, tighten the L-screw, in small increments, until the gap closes."
But I've tightened the L screw all the way and there is still a massive gap....? (I can make the gap larger by loosening it but obviously that's not what I want)
What have I missed?
