676-14546-00 – Float Needle Valve – Yamaha

The 6761454600 float valve is a genuine Yamaha outboard carburetor needle valve. It works inside the carburetor to control fuel flow into the float bowl. This valve keeps the fuel level steady as the engine runs. Because it matches Yamaha’s factory design, it fits directly into compatible carburetor assemblies without modification.

In simple terms, this float valve helps prevent fuel overflow and flooding in your engine. When the fuel bowl fills, the float presses against the valve. Then, the valve shuts off fuel flow. Also, when fuel drops during use, the valve opens and lets more fuel in. As a result, your engine gets the right amount of fuel for smooth running from start to idle and through throttle changes.

You install the 6761454600 float valve in the carburetor during rebuilds or maintenance. Often, engines with worn or sticky valves run poorly. They may hesitate, bog, or flood after sit-ups. Replacing the needle valve restores proper fuel control and makes tuning easier. Moreover, this part resists corrosion and holds precision fit even after hours on saltwater or fresh water.

Additionally, this valve works with the float and seat to maintain exact fuel level. That balance helps your Yamaha engine start easily and perform reliably. Therefore, replacing old or damaged valves can bring back stable idle and better throttle response.
