An ATV can overrev due to several factors, including a malfunctioning throttle cable that sticks open, allowing the engine to receive too much air and fuel. Additionally, a faulty or misadjusted carburetor can lead to an improper air-fuel mixture, resulting in excessive RPMs. Other causes may include engine modifications that alter performance characteristics or issues with the ignition system. Regular maintenance and proper tuning are essential to prevent overrevving.

Crappy seals. Take the ATV to a local workshop and tell them that you suspect the seals on the carburettor to be shoddy. OR it could be a float problem : sticking float will let fule run out the over flow pipe.
Dirty carborator. If its been sitting for awhile the carborator collects dust and other crap in there and clogs it up.
