Small Engine Troubleshooting Problems? Ask a Mechanic Now.
HI, my name is***** will be assisting you.
The easiest way to identify your problem will be to unplug the ground wire that is going to the ignition coil and see if the engine will fire to the plug then. If it doesn't then the coil is bad, if it does then there is a problem with the wiring or the switch.
You will need to remove the pull start housing from the engine, the ignition coil will be mounted right beside the flywheel, there is a small wire that plugs onto it that you can unplug then try and see if you have spark or not.
Let me know what you find, if you still need assistance we can continue our conversation here.
