I replaced the MB stock wiring because it was heavy and blocking the guide movement. I replaced the wire with thin flexible wire, much shorter and still had trouble with the wire hanging up on something. My flashlight showed the wire was grabbing the 2 brake ducts that poked a good 6 mm into the wire travel area. The ducts are gone now. I also replaced the stock stiff contact braids.
I have two tungsten weights, one in front of the motor in the clip place and one shoegooed on the front of the chassis. Does not stop the perpendicular pinch on the last S turn yellow lane. The wires are not holding the guide perpendicular any more, but the dust is letting the guide rotate all of the way as the back end slides wide. I may remove each weight and both weights since David says the Opel is not using any, and just drive like I did in the snow.
I tried the pink gear and it is real squirrely. Not smooth driving, but David’s is. going to back off a tooth or two. Good luck driving it. I am sorry some one else has to drive it.
I am happy to run an MB on which I learned to drive stick shift in 1964. My Dad was quite brave to let me learn on the 1961 220S he brought home from Germany after his tire company assignment. Then the Vienna taxi company had them and my Dad bought a diesel in the 2000’s.
