Yamaha - Float Chamber Body Carburetor Component 6AH-14980-00-00. Overview. On smaller Yamaha carbureted engines, the float chamber body is what keeps fuel delivery steady and reliable. If it's worn or not sealing right, you'll start noticing rough idle or inconsistent performance pretty quickly. I've worked on motors where fuel issues came down to this exact part being off. When it's in good shape, fuel stays regulated and the engine runs smooth from idle to throttle..
