I hope this is in the right place, and I did a search, but didn't come up with much...
I recently bought a 92' Montgomery Wards lawn tractor with an 18 hp BS v-twin engine. The guy I bought it from told me he had to choke it to shut it off, and when I got it home, it seemed like I had no power to the ignition switch to start it.
I picked up an MTD ignition switch today(7 blade harness), and still couldn't start it, after playing with the ground from the starter to the chassis for a second, I was able to use the ignition to start it, but it still won't shut down when I turn the key to off. It is currently in storage, so I wanted to get a few ideas on where to start looking for problems.
Just a quick glance shows me he added a flood light to the snow blower, and I thought maybe a wire sheath has rubbed off and is shorting out some where, but I would think this would cause it to stall correct? I also saw he tapped the extra light into the actual light switch, and it acts as it should, being that the engine has to be running for the lights to work(says that in the manual). Other than that modification, I can't see any other splices in the harness, and thought maybe ya'll had an idea of something simple, or had dealt with this before, like I said, it's in a storage unit, and I don't currently have access to most of my tools and meter.
