That doesn't look like much travel. Maybe enough if the TO bearing was already touching the PP arms. If it were me, I would modify the arm so that when the slack was out of the travel to the PP, I would want the arm to be farther back toward the pedals. Maybe drill another pin hole to hold it on the shaft clocked a bit clockwise. Maybe you are not getting enough travel to completely disengage the clutch.
