Review on 🔧 Aftermarket Replacement Carburetor for Tecumseh 640262A - Optimize Your Search! by Ashwin Drollinger

Float valve does not work, creating a risk of fire due to fuel leaking from the carburetor. I had to open the float chamber, remove the float and adjust the float by bending the metal tab "up" to increase the pressure on the needle valve. This prevented fuel from leaking through the carburetor. In addition, the rubber seal of the float chamber expands when it comes into contact with fuel, so the seal cannot be reinserted immediately after opening the float chamber. In order to achieve a good seal, the gasket must first be dried to shrink before joining the gasket and the chamber, otherwise the fuel will leak out of the chamber.
