Ignition shut off not working??

[racerone3]

So if you have tried grounding the stud, coming out from the right hand side of engine looking at it, to a good ground and nothing happens, I would assume the diode wire has gone bad. That would involve removing the shroud for access.
This is assuming you are working on a B&S.

Typically if the diode goes bad it kills spark to one cylinder (rear one). perhaps the diode wire is MIA or at minimum not hooked to the ground stud inside the flywheel cover

I will pull the rear plug and check for spark. As slow as this thing is, it would make sense if there is no spark and only running on 1 cyl.

Any advice on removing the rubber thing between the motor and the side air inlet??

What I would do is pull the shroud off and make sure that the wires to both coils are hooked up and if so check the diode in the kill wire, utube has tutorials on all this stuff, then you will know what wire should go to ground. Then using a test light, determine which wire to your ignition switch goes to ground when the key is in the off position. The black wire from your coils hooks into that wire. Be aware that if you feed 12 volts into that black wire you may fry your coils, or diode. Not 100% sure on that, but read that somewhere. Just make sure the black wire from the coils goes to ground. A real pain in the butt, but may solve your problem.

we spent the morning trying to get the air funnel off and out of the way,,ended up cutting it in half so I could get the engine shroud off. Found both the ground wire and the plug wire had been chewed in half and the coil has gnaw marks on it. It has only been running on 1 cyl that's why it's such a Dog! The only coils I can find are for an Intek 16-22 hp I hope they interchange?? Local shop wants $60 per coil.

It boggles my mind how Argo can still be in business and Max is gone. Argo is a complete mechanical nightmare.

Update :

New coils on, figured out the wiring,,took it for a short blast,,the Briggs doesn't have the power that I expected,,but it's Ok. I have to work for the next few days so we won't get to play with it until the weekend. I think right now the Governor is my biggest issue. I'm used to 2cyl -2stroke power,,

haven't resolved mine yet too hot weatherwise but I have realized something that might be a silver lining. I just went to start up my Honda 350x which I've owned almost 2 years now and never an issue. haven't riden it really since last fall but have started it occassionally every month or two. I just went to start it and now the carb needs a good cleaning even though I treated the fuel. Will run on choke but not without it. So back to the argo since I installed this motor and wired it as such, not a mechanic and tried to replicate the previous motor wiring, I never get the gummed up carb as it shuts down due to fuel starvation instead. Always runs and runs well as is so maybe I'll leave it as is.
