I bought the bike as a non running project. I removed and cleaned the carburetor and after re-installing it turned it over to make sure it had a spark. It did. I then fixed the sticky throttle cable and handle, and when I tried to turn it over again, NO SPARK! All of the lights come on, the starter and engine turn freely, the coils are getting power, but no spark. What should I check next? Is it as simple as both coils spontaneously failed? That doesn't seem plausible.
Thanks!

I will upload pics when I get home tonight.
