I literally had this exact same problem, fit everything together, the valve rotated perfectly until the bolts were tightened and then the valve was stuck in place. I believe that it was the end stops in the cover pressing down on the valve and by re-assembling with the valve in the alternate orientation the issue went away. I can only refer back to Pat's page for photo's that might demonstrate how this can happen - https://www.cartestsoftware.com/fz1/exup...nance.html
I just went to service mine and noticed one of the cables had snapped, no OEM replacements so went for the Wemoto SlinkyGlide ones, will post back when fitted.
