Small Engine Troubleshooting Problems? Ask a Mechanic Now.
good morning Linda my name is ***** ***** ill see what I can do to help
first off, what is this engine in?
your on the right track, shorting the coil to ground is how they are normally shut down. this engine keeps running with the coil disconnected?? does it blow excessive black smoke when this happens?
ok so are we thinking there is an issue in the key switch? which is what should control your ground
then at this point I would be looking at the connection between the key switch and the coil ground. they system is very simple in that it is a single wire that grounds the coil when the key is in the off position.
