Briggs pull start mower. Someone gave it to me and said if I could get it running I could keep it. It was leaking fuel around the carb bowl. I replaced the fuel
line, went over the carb and replaced some parts and discovered the throttle cable was broken so replaced that. It also has a new spark plug and air filter. The problem now is it won't turn off without me pulling the spark plug wire. I posted pics of what is attached to the throttle cable. I think that what is supposed to happen is when the throttle is moved to off, the mechanism acts as a switch and is supposed to ground the spark plug to the frame. The first pic is the top view, the second is the side view. In the second pic the wire running off to the left runs under the engine housing. It's unclear to me why the short wire is there at all. It seems to be firmly attached. I haven't taken the housing off because I'd have to take the start assembly off and I swore after my first one that I'd never do another starter recoil spring. The mechanism does move the way it is supposed to. The choke and throttle work otherwise. I can't find a parts diagram for this to see if I understand correctly how it is supposed to work. I'm wondering about just wiring in a kill switch.
