This should help. I know its a different quad, but same principle

every four wheeler I've ever worked on has the ignition timing fixed and controlled by the CDI. Mechanical timing usually invovles lining up the T on the flywheel with a mark on the cam shaft. you'll need a service manual for more specifics.

Make and model please and the year if possible.

could be lots of things from the spark plug to the stator or even the cdi. you'll need a service manual and a multimeter to test it all.

Dead battery or solenoid

push it off a cliff

Bad temp sensor or bad fan motor
