Can't get it to shut down

I'm OK with engines and repairs, yet weak in the electrical and ignition systems. So, I have a 5 HP Tecumseh that has both a key on/off switch on the dash, and the throttle lever also rubs against the ground wire that is one the side of the shroud.

BUT, neither the key nor the throttle lever touching the ground wire results in the engine shutting off.

What would cause this? Perhaps the ground wire is not actually grounding out the engine? Any steps for me to take to get this engine to shut down?

The wire to the coil itself must be open somewhere.
Can you follow the wire under the flywheel cover?

+1 on the open wire. Gently tug on it and see if it is loose.

Thanks guys -- I'll pull the shroud and check to see if the wire is broken. While the shroud is off, that's a good time to replace the fuel line at the same time.

Best way to check out the wire physically and an excellent excuse to replace the fuel line.
You could also try to check the wire for continuity. In your case not really worth the effort as you already know it's open somewhere and it's pretty likely to be under the cover.

Make sure the windows are up before the snow plow goes by !!

Just to close the loop....yep, it was a broken wire at the coil, and some pretty worn areas through the insulator covering that was causing the problem.

Thanks for teaching me something guys!
