cannot tell from the pic but on the rear derailleur you should have a couple screws signified by an "H" and an "L". your L screw needs turn in to stop the derailleur from moving to far inward. the pulley needs to be directly under the big cog. turn about 1/4 turn increments til desired results

If you feel stupid twice, does that make you a re-tard?
