Re: shorting throtle cable
If the cable is attached to the carb by a screw clamp, you can shorten it to any length you need just by cutting with wire cutters, dremmel, muffler cut off tool, etc. The cable cover needs to be cut with a dremmel type device so that it doesn't get crimped and restrict the movement of the cable through it. You could probably use a grinder to cut the cover.
Caution! I give opinions as if they were worth something. Use at your own risk.
