I have a Stowe mortar mixer with a Honda GX240 engine, and it's ran wonderful for the year I've had it. It's an older unit, no idea how old. I was running it the other day and it quit, like I walked over and turned off the ignition. Now it won't start. I checked to make sure it had enough oil, thinking it could be the sensor, but that wasn't it. Seemed electrical for sure, given how it quit and hasn't burped since. I got a wire diagram and this engine has clearly been "repaired" as it doesn't exactly match the factory wiring. The 2wires in the photo were in a sleeve together but not connected to each other or anything so I think the is where my proble is. Any ideas?
