Hey guys new to jet skis and this is my first 750. How can I identify what carburetor I have? It is mostly stock, and it still has the factory original carb. Also, what does BN or SBN mean in terms of carbs? I also have an '88 650sx stock and a '91 650sx stock, what carbs would those have and how can they be identified? Is the model # for the carb stamped somewhere? Thanks guys and awesome site, 1 minute after finding this site I was registering for membership
