As far as I have seen this might be a new trick. Instead of using a rubber band or o-ring or just unhooking the darn thing! Last night while messing around on the sled I figured out that if you take the switch out of the housing, pop the bottom off and switch sides with each wires location it reverses the function of the switch so now when I pull up on the button the engine dies and when pushed down it is in run mode. :face-icon-small-coo I don't see myself accidently pulling the switch up while in a technical spot or in the trees. Thought someone else might like to know this little tid-bit.
