What thumper said.
From memory (which is failing more and more each day), I know your favorite British guy mentions some "fiddling" with the springs, and has a trick in the video....or maybe that's a different video, that covers the reassembly.
FWIW....I remember the head of my torx screw being very close to almost level with 3a (maybe 1 or 2 or 3 threads showing, on the torx head side). It was set this way from the factory. I did not mess with it.
