FIRST of all you need to understand the basics.

The Limit screws do just what the name implies. They determine the extreme limits in the FD's range of travel. They don't control the position which is controlled by the cable.

So, let's get back to the FD and get it dialed in.

First, let's reset the outer limit. (you'll need a stand, friend, or a way to hold the bike up with the wheel off the ground)

Shift to the inner ring. Now, disregard the levers and shift to the outer ring by pulling the bare wire away from the frame. Back off the outer limit until you can make the chain overshift and fall off the outside. Now bring the limit in by degrees until you cannot overshift, no matter hard you try. (later if you ever overshift, you'll bring it in another hair, but no more).

With the outer limit set, use the lever to shift to the outer and note the position. If it's not right, you'll need to adjust the cable length (tension) using the adjuster (if you have one), or by pulling it down in the pinch bolt. It's the cable that's key to getting the outer cage correctly positioned in high, so take your time and get it right. (A trick to make setting the cable in the pinch bolt easier is to jam a pencil into the FD mechanism to hold it out, while shifting to low to slacken the cable).

Finally, you'll set the inner limit, so it correctly trims the FD in low, when the cable is slack.
