On / off switch wires on a Briggs and Stratton engine

Hey everyone! My snowblower won't start and it has a Briggs and Stratton engine on it (pull cord no electric) and when I was inspecting it I see only one wire coming from the on / off switch. It clearly looks like there should be another one but I can't find where it would be.

Does anybody know where the wires typically run? I know one should go to a ground but where would the other one connect to / from? Or should there only be one wire and I need to find the real culprit for the engine not starting?

Thanks!

That is the only wire. When that wire gets grounded the engine wont start.
Usually you'll find that wire attached to the bottom of the mechanism where you adjust the operating speed from slow to fast.
When you put the speed all the way to low.....usually all the way down.....a metal clip will short out that wire killing the engine.

You could leave that wire open (unconnected) to see if the switch plate has an issue.

In re-reading your post....you have an on-off switch. That switch must short that wire to ground when in off position. Same diagnosis....disconnect it and see if engine will start.
