yeah CDI or coil are two things to check. also the stator. there's a test that you hook up an ohmmeter to your stator outputs and get the reading. there should be a specific reading for your machine, i'm unaware of it, i apologize. if that reading isn't right, then your stator may not be working properly.
however you mentioned you can see a spark. in that case the stator is working at least. i would test the stator anyway, then you can determine if its functioning correctly. if it is, then try to find a known good CDI to swap in the quad. then if spark enough to start, your CDI was bad, if no spark, the coil is probably to blame.
also, the killswitch system could have a fault, as well as the harness itself.

here is a test to check the stator. scroll down to etondaddy's second post. you will need an ohmmeter.

in fact, you have an eton as well, so the results should be similar.

You can download the manuals for eton quads for free at www.anythingatv.com. You can also download just the wiring diagrams, though the diagrams are also imbedded in the manual so I'd recommend just getting manual and printing it out. There are some troubleshooting guides on the anythingatv site as well.
First thing to check:
Do you have spark? Pull out the plug, hook it back up, and hold the threads against the engine block while cranking the starter. Look for spark at the plug gap.

Is the spark plug wet?..If not try putting a splash of gas in the carb (with the air filter removed for access) and see what happens..The carb may be getting gas but that doesn't mean it is getting into the engine....The spark isn't overly big on these anyway so that may not be the problem...I replaced the stator on our viper last year due to a weak looking spark and it turned out to be a non related problem that was causing my issues..
