This is a genuine OEM sourced component which is specially designed for use with Honda engines commonly installed on lawn and garden equipment. The ignition module also known as armature-magneto provides the current for the ignition system by producing pulses of high voltage for the spark plugs. It is made out of high-quality materials and is sold as an individual assembly. A wrench set will be needed to replace this component. Check the diagrams for your model to ensure the correct repair procedure.

    Still having problems with no spark. I think the boot on end of coil where metal contact is is not making a good contact.
    Part was delivered by the time it said.
