Parts for Craftsman 143256032: Carburetor No. 631449 Parts

Here is a replacement welch plug for use with the carburetor on small engines and various pieces of outdoor lawn equipment. It is important for a carburetor to have a tight seal, which will prevent an influx of air and cause issues with the fuel mixture. The welch plug is meant to prevent these issues. Over time, the plug could have lost its seal, it could have become corroded, or cracked, or it could have become lost. This could cause a loss of power or for the engine to run rough. Owners must replace the welch plug as soon as possible to avoid issues with their engine. This welch plug is a genuine OEM replacement part that is sold separately. The plug can be used on many different types of small engines and lawn equipment, such as lawn mowers, snowblowers, lawn tractors, and chippers. Compatible brands include Craftsman, Toro, MTD, Lawn-Boy, Cub Cadet, and Tecumseh.

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.

The float shaft and pin are a genuine replacement for select Tecumseh carburetors on small lawn and garden equipment engines. The float shaft and pin are responsible for maintaining the fuel level within the carburetor. Over time because of repetitive motion, the float pin and shaft can break or become damaged, which will stop the carburetor from functioning properly. If the carburetor cannot function, the engine will not be able to perform. If left unattended, the engine and carburetor could fail completely or bigger issues could occur. Replacing the float is essential to getting the equipment back in order. This genuine float shaft and pin is designed for use on machines from Tecumseh, Poulan, Husqvarna, Lawn Boy, Cub Cadet, MTD, and Craftsman, and is compatible with a number of models. The fuel system should be drained and the engine should be cool before any engine repairs are started. Always wear gloves for hand protection. This float shaft and pin are made of durable materials and sold as a unit. No additional hardware or parts are included.

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. You’ll have the assurance that this replacement is manufactured according to Tecumseh’s highest standards. It is compatible with mowers, tractors, and snowblowers from Toro, Cub Cadet, Lawn-Boy, MTD, and Tecumseh. This part is sold individually.
