I pulled my Old Suzuki Ozark 250 out of the shed after 4 years. The tank wasn’t ran dry so I drained it and cleaned the carb without taking it off(per the can). The bike fired right up and runs. It idles perfect and runs smooth on flat terrain. My problem starts when the ATV is not level and I’m riding. It starts sputtering, spitting, and occasional back fire like it’s not getting enough fuel... if I go down a hill it usually dies off. If I try crossing a stream and go down the bank spit and sputter. In the stream it’s fine. When you go to ascend looses power. Any suggestions? Sent from my iPhone using Tapatalk
