I had that problem with my cat 550 and it was frm the solder hitting the plastic cover on the cable. Even tho I had it fine there was just the slightest bit catching and keep it from from opening all the way. It looks as if you don't have much travel till you hit the connecter on the cable.
Instead of looping back up and around , can you come up to it and reverse the servo so there wouldn't be so much flex on the cable? I'm thinking less cable less chance of flexing to a point that it takes away from you getting WOT.
Just a couple of thoughts taht worked for me and the K&B on my cat sits waaay back from the gear.
