Small Engine Troubleshooting Problems? Ask a Mechanic Now.
Hi, my name is ***** ***** me review the issue, and I will be more than happy to help resolve it as quickly as possible.
IF you can start the machine by unplugging/removing the ground wire from the coil, the coil is bad. The coil is grounding itself out internally and will not start with wire connected. By doing this of course there is no way to turn engine off unless you disconnect the wire or choke out. Replace the coil and you will be back to proper running order
