been having issue with my ns40c , it spits and sputters when in gear. runs fine in nuetral. if you give it throttle quickly it does this but if you slowly push the throttle it does ok. but seems to clear up abit when the choke is halfway out. i have cleaned the carbs , new plugs, new gas. but i just found that the gas line connector at the motor is leaking from the o ring. could this cause this?
