Item #1567830 | Briggs & Stratton Genuine OEM Part #231855S
Carburetor fuel inlet needle. This needle can get stuck if fuel if left inside the carburetor for extended periods of time. Ethanol in the gasoline can cause it to turn into a varnish-like substance and cause the engine to not start.
We recommend using fuel stabilizer to keep your fuel fresh and protect your engine from corrosion.
