Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is***** will be assisting you.
I would agree with your mechanic on the oil sensor, it could be an issue which would cause this problem. I have never had an exhaust sensor cause this problem however. I would be looking at the start relay, voltage output from the genset, or the control board on the machine. Typically this problem is caused by either the oil sensor or the start relay.
