Had a spare Tors, so thought I'd try a idle screw solution. I already had the tap and fine thread 5/16" bolt and jam nut. If you have to go out and buy a tap, it probably makes more since to buy the tors elimination kit off ebay. If your on a budget and have access to a tap this home brew method may be a little cheaper. I have not tried this on the motor yet, and think the screw could be a little shorter, then cut in a new slot. Also, this aluminum housing is pretty soft material, so I'm not sure how the threads will hold up over time.
First, remove the tors switch, and factory idle screw.
Tap hole with a 5/16x24 tap, no drilling required. I used a fine thread tap to give it a few more threads.
Install your bolt. I cut off the head, and then cut a slot in the end with a angle grinder and cut off blade.
Use the original grommet and some silicone or maybe just squeeze in some silicone to seal up the space where the two wires went through.
