The first thing I would do is purchase a repair manual, it will have some direct resistance tests for some of your ignition components as well as a troubleshooting guide. Most likely problem is a bad coil, CDI, pickup coil or just a loose or corroded connection somewhere. A visual inspection of everything behind the stator cover and all the ignition wiring and switches would be a good place to start, but I would strongly recommend getting that manual.

I would check for power into and out of the coil by the use of you ignition diaphram. if you have power in and out then i would test for ground in the circuit by putting the test light to power on the gatorclip and touching the ground wire in the plug. if all is ok then replace the coil. if you had weak spark then no spark i would suspect a wiring issue or a poor battery as well.
