The threaded adjuster where the housing ends on the downtube is exactly what I'm referring to. Once the cable is under tension, turning it outward will tighten it moving the FD outward (except if it's against the outer limit). When starting our it should be threaded all the way in so you can use them to tighten the cable later.

People often have trouble pulling all the slack out of the cable, so pull the FD outward (by pulling the cage itself out) then take up the slack and tightening the pinch bolt. Now when you let go, the FD will move back in taking up the remaining slack. Be careful not to get carried away, or the you could end up with the cable too tight. But with some practice you'll dial this in and get good results.

Also I didn't say this earlier, but often folks don't fully seat the housing in the ferrules, or into the lever, or cable stops. They pull out all the slack but once they try to shift things settle creating more slack. The key is to seat everything and get the slack out, even if it takes more than one try.

BTW- there are a number of tutorials available on the net, free or pay to view, in both print and photos, or video format. Search "front derailleur setup" for a nice selection and review a few until you get a good sense of how it's done.
