You'll figure it out.
Remove cables from the pulley on the barrel.
Remove pulley.
You'll suss it by that stage.

With the pulley removed, the RC valves should be easy enough to move by hand using just the valve shaft. If not they'll need cleaning.

Once the illignment problem is solved and the valves are clean, adjust the cables as per Directions <<<Click
