help with front derailluer

i know it seems like such an easy setting but i cannot seem to get the FD adjusted correctly.

setup:
10speed road bike
shimano FD-6600 and FC-6600 (double) and RD-6600, STI 6600

symptom:
when in the large chain ring the FD does not extend far enough.
I can pull the cable tight and it will extend to exactly where I want it.

question:
how to properly adjust the cable tension?

I tried holding the FD in the position I want and then lock the cable in that position. this works, but then I cannot switch to the small chainring.

I messed with the barrel adjuster but it doesnt ever seem to make the cable tight enough to move the FD.

I'm sure I missed some key detail that will help someone solve this simple matter, so please ask.
I will post some pics in a few just to hope and get some more ideas.

thanks

assuming your shifter throw is proper and your derailleur fits the chainrings then the following procedure should work.

Unfasten the cable from the derailleur so the derailure rests on the low limit screw (ensure that this is set properly) and bring the chain to the inner chainring. Then set the barrel adjuster so that you can adjust it either way (usually 50/50 is good, though I tend to give a little more room to tighten). Set the shifter to the first/lowest chainring (loosest tension). Then pull the slack out of the cable, with out pulling on it tightly, and re-clamp it to the deraillure.

If this standard procedure doesn't work, then ensure that the derailure is properly fastened to the frame, and check your specs for compatability.
