apjvicta,
Ok is the silver box loose?
If so you will need to replace the screw or pop rivet. Your problem could be a bad earth or the electronic module is faulty.
It is not very often that a coil goes it is usually the module and the replacement cost is about $30-00. :Wavey:
Also what you can do is remove one of the wires in the carby to see if you get spark back.
We have information on the carby and electrical under parts list and manuals area in this section.
