Parts for Craftsman 640096: Carburetor - 640096 Parts

The primary function of a carburetor is to mix fuel and air in the right ratio. Fuel enters the carburetor through the fuel inlet fitting and then to the float bowl which delivers fuel to the other circuits. From there, the fuel goes to the needle valve, which is actuated by the float. When there is insufficient fuel, the float will stay down, keeping the valve open. Once the chamber has enough fuel, the float will go up and close the valve. A failed float bowl may leak or have too many dirt particles deposits that impede fuel flow. Luckily, you can easily replace a busted float bowl. This part is a genuine OEM Tecumseh 631867 float bowl replacement.

Carburetors must have tight seals to prevent too much air from getting into the carburetor at one time. If there are issues with a welch plug, it could cause an engine to lose power or to run rough. The plug might have lost its seal, it could have cracked, or it could have become lost. Sometimes, the vibration of the engine is enough to cause a plug to fall out if it is not tightly sealed. A loose fit will cause problems with the flow of fuel. This genuine OEM welch plug is sold individually and can help to seal your carburetor so your engine retains power. The part can be used with a range of lawn tractors, lawnmowers, snowblowers, and small engines. Compatible brands include Tecumseh, Lawn-Boy, Toro, Craftsman, and MTD.
