Yamaha - Float Chamber Assembly Carburetor Fuel Control Component 6P2-14180-51-00. Overview. The float chamber is where your fuel system really settles down and does its job. I've worked on plenty of carbureted Yamahas where rough idle or hesitation came back to issues inside this housing. When it's clean and functioning right, fuel levels stay steady and the engine runs smooth without surging. It's not flashy, but it's one of the key pieces that keeps your carburetor behaving the way it should..
