Yamaha - Float Chamber Gasket Carburetor Sealing Component 6A1-14384-00-00. Overview. When a carburetor starts leaking or running uneven, a lot of times it comes down to a worn gasket in the float bowl. This gasket seals the chamber where fuel sits before it's pulled into the engine, so it has to stay tight and consistent. Once it dries out or gets brittle, you'll start seeing leaks or fuel issues that are hard to ignore. It's a small part, but it makes a big difference in keeping your carb working the way it should..
