Attention!!!!! Correction. I just posted "The 4th reply to that forum thread is by "prestonjb" with instructions that involve removing the cable before you adjust the H and L screw. Have you tried that ? When I did I could now see the H screw moving the front derailleur" but I just tried to do it to my bike again and actually didn't see the derailleur move when I turned the H screw. At any rate it helped me out.
