I'm pretty sure I'm buying a new carb for my '01 Warrior. I just can't get this one to work right. I'm looking at a White Brothers Flat slide by Mikuni without an accelerator pump. The one with the pump is like another 200 bucks more, and from experience with this stock carb on my warrior the pump seems to give it problems. What is your guys experience with this accel pump system, is it worth it or will I not even notice the difference.
