Not sure if your aware but down where the cable mounts in bracket on the clutch cover is where you adjust outer sheath length. Yours pictured below
See how all of your threads are on one side of the mount marked in yellow and just about none on top marked with red. Try about 9 threads on the bottom and the rest up top.
Also you lifter shaft arm does not look like its on the normal position. By this I mean its more toward 6 O'clock verses the normal 2 or 3 O'clock like below
I can't make it out but there is a alignment dot on the lifter shaft and the shaft actuation arm. Marked with yellow below.
Now one real early rockets there was not a mark on the arm but the shafts had one. I set them referencing the shaft dot and the slit in the actuator arm. You can count the spline teeth on mine above fore the offset. Anyway the placement of the arm is important so the cable pulls the arm in a rotation. To me yours apears that being to far it pulls straight against the shaft before it starts to rotate it. This could work against you and the feel for freeplay adjustment. I'll let you absorb this and ask questions if it needs more clarifications.
