Great carb... Huge compared to my stock 110cc china carb, bolted right on though. I could feel the huge increase in power. The only thing I was not too happy about was; There was no option to choose jet size when I bought it, so it came very rich. It also didn't come with anything to tell you how to use the choke lever. So for people who do not know: Lever up= Choke on, Lever down=Choke off. One more thing; The choke isn't a real choke, It just richens the fuel more. I like it better that way. The money is well worth it!
