Ok guys thanks for the ideas , keep them coming just incase it still persists. oh and also when climbing the hills it would go like have half way up and just seem to slow down and then just wouldn't go any farther just like it had no more power and you could hear the motor straining to make it move .

Someone also said to me maybe pluged fuel filter or pluged up exhaust too much back pressure when trying to make it work hard ??

Just pick up the atv for the kid , it starts great , runs great , doesn't smoke , on the trails no problem but as soon as you try to climb any kind of a good hill or mud hole it's like you hit a wall and there is no power to keep going . It just runs out of jam and it will just sit there and go no farther with the throdle wide open . Any ideas pls
