when i start the 4 wheeler, it has a hard time turning over, it has a new plug and battery. the fuel is on and choke. it runs for a little ideling, then cuts off. when i get it running good- while holding the throttle, i can ride it. when i start slowing down, it starts sputtering, and it sounds like its coming from the top of the motor, between the piston and spark plug. let me know what u think i should do. its either not geting gas, or enoguh air when i start slowing down

 

did you try cleaning the carb?

 

yea sounds like a dirty carb, make sure its got a clean airfilter and theres no air leaks in the intake boot or anything also.
