I'm not familiar with all quads and all the kill switch locations. Does it have a tip-over kill switch? Is it working? Is the quad in neutral? Is the neutral light on? Many engines will not spark if the neutral light is not on. Are the headlights off when starting?
How good is your battery? A low battery can kill spark. Test for spark by grounding the threads of the plug against the cylinder. Have a friend kick the bike while you watch for spark. Assuming no spark, then check all the kill switches with an Ohmmeter to be sure each switch is working properly. Sometimes a switch goes bad. Try disconnecting all kill switches then check spark.
Check the wiring harness, even under the gas tank and seat. Are all the connectors clean and with a tight connection? Any abraded wires? Check the ignition switch also. The switch can go bad as well. Are the flywheel coils good > is the battery getting a charge?
Still no spark? If CDI then get it checked.
If points then file or replace them along with a new condensor and reset the gap then time the engine. >> I hope this helps.
Please rate this answer. Thanks trsrhntr!

I see: you changed the plug because it was backfiring.
Does it back fire when you let OFF the throttle after revving it, or does it back fire while being revved?
If it does it when you let off then Ollie's suggeston might do it. If that doesn't do it then check for dirt in your pilot jet.
If it back fires when revved up high could be dirt in your main jet.

I would follow the fuel line all the way check the filter it should be inline and check the pump as well i would say its one of them two.
