    If the chain will not go to either end of the cassette both limit screws need winding out until it does.

    If the trouble is with getting the gears to index over the full range of sprockets check that you have the cable on the correct side of the mech clamp, it should be on the wheel side.

    When you clamp the cable to the rear mech it should be positioned on the wheelside of the clamp bolt. if it is on the other side your gears will never index properly.

    Re the limit screws, they should only be wound out enough to allow the chain to sit on the smallest and largest sprocket or the chain will overshoot the cassette.

    www.parktool.com has plenty of photos to explain. Joe means that the cable should be on the lower side of the clamp.
    Make mine an Italian, with Campagnolo on the side..
