I have a 2005 Kawasaki prairie 360 and I added a new carb but when you go and give it gas afte like 1/4 throttle it will just pop and sputter won’t rev very high. When I first put carb on it would go good fast as you wanted for like 2 minutes then when I slowed down it just started it’s sputtering and popping and has done it ever since guy I got it from said it just had motor work. But others are saying they think it’s the motor
