L Limit screw can get front derailleur close enough 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?

What I was missing was that the screw wasn't fully tightened but it was impossible to tighten the screw whilst the derailleur was against the limit and the cable was tight. Pulling the cable to move the derailleur and tightening the screw at the same time worked fine. Totally slack cable would have been fine as well I think.
