atv will start and idle but when I give it gas it hesitates and then will either rev up or die and then after a few minutes will shut off. It will start and idle almost every time but does the same thing. Removed the carb and checked the jets and bowl and alls clean. checked fuel and tank and valve is working correctly. any ideas? thanks

 

Dose it run a little better with the choke on? There is a small screen in the inlet tube on the carb that can plug up. Pull the fuel line off of the carb and use a can of carb clean and a soft wire to clean it out.
