There are other ways than using the stock parts.
I had an old choke cable off a lawn mower. Cut it to length, bent the end of the wire to hook to the enrichener of the carb, clamp under the cable clamp. Infinitely adjustable.
Hears some pics.
You can buy new cables at most parts stores.
Another thing is to replace the bar mounted lever cable with one like Honda uses on my CM400, probably many others. It mounts on a riser bolt and has a pull knob. Again infinitely adjustable. No pics of that.
