After having a ton of issues with the stock carb, I just decided to go ahead and replace the whole thing. I started looking at OEM carbs new/used, but they were so damn expensive. So I jumped on ebay and found a brand new carb made by Zoom Zoom for $93. I was hesitant at first, but I said the hell with it and gave it a try. First of all it shipped super fast. Second after hooking it all up, I crossed my fingers and to my surprise it fired right up. After a few Idle adjustments she runs better than ever. Seriously. It has more power/speed than before I started having carb issues. So to anyone that is on the fence, I say go for it. I am not expecting it to last forever, but for $93 you cant go wrong.
