When adjusting a countermarch loom always ensure the pegs are in the castle.
If you are struggling to find a solution put the pegs back in the castle and check everything has been set up correctly. Starting at the top of the loom check all ties are still tightly tied and that the shafts, lamms and treadles are exactly straight/horizontal and all line up. This is the main cause of problems on a countermarch loom
