I can understand your concern about replacing the ignition module. The housing will need to be taken apart and you will need to gain access to the flywheel. The individual parts shown below will need to be removed to access the module. Unless you feel confident in your repair skills, I recommend taking this to the nearest repair center and have a technician make this repair. I'm listing a site you can access, for the nearest repair center. Here is a link that will provide the nearest drop-off locations:
