I’ve gone through decagons, cleaning the parts, lightly lubing the tracer board, and adjusting the switches, and if they’re still sluggish getting to 9, I use Clay’s trick of shortening the return spring. That’s pretty much worked every time. Even with switches adjusted properly, there’s a lot of resistance built into the design pushing all the switches over at 9. I guess it’s still a “shortcut,” but it’s not a “hack” like drilling a hole in the cab to pull a string to manually activate a relay.
