Craftsman Carburetor

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.

This is a carburetor bowl. It holds the gas that is mixed with air before it enters the engine. The carburetor bowl contains a float which regulates the amount of gas needed to mix and fuel the engine.There are times when the carburetor in of itself is considered in good working order but the bowl may be compromised. This can happen if the bowl has been corroded. Rust will damage the carburetor bowl and render it ineffective. When replacing the carburetor bowl, be sure to work in a well-ventilated area and to wear the proper gear when handling engine parts. Once the carburetor is free from the engine, unscrew the bowl from the unit over a catch pan. Any contents will fall into the pan. Disassemble the old bowl's hardware and use it when installing the new bowl.This is a genuine OEM part manufactured by Tecumseh. It is compatible for Toro, Cub Cadet, and MTD engines.

This part is an inlet needle. This inlet needle works like a valve to transport fuel into the carburetor bowl when the bowl has drained and then stops fuel intake when the carburetor bowl is full. A new inlet needle may be needed if the fuel is not flowing into the bowl as it is supposed to. This can be evident if the carburetor floods or if the engine does not have enough fuel when it's operating at high speeds. A visual inspection of the inlet needle can also be a good indicator of whether or not it needs to be replaced. If any physical signs of damage are present, the inlet needle will need to be replaced. Remember to wear gloves when operating or performing care and maintenance on any outdoor power equipment machines.This part is a genuine Tecumseh part and is an OEM part sourced directly from the manufacturer and it is sold individually. This inlet needle is compatible with snowblowers manufactured by Tecumseh and Toro.

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.

This is a replacement carburetor used with a wide variety of lawn and garden equipment. It includes the full assembly for the carburetor and is responsible for mixing air and fuel together before both are transferred to the engine's combustion chamber. If the carburetor is damaged, the engine may not start as expected, even when the fuel tank is full. Carburetors can also become clogged by dirt or other debris.If the engine is not starting as expected and there is plenty of fuel in the tank, the best thing to do is test the carburetor for problems. This involves adding around a teaspoon of fuel to the carburetor itself after removing the air filter. If the carburetor is the problem, the engine should start but will quickly shut off. A socket set, pliers, and a screwdriver will be needed to replace the part.This carburetor is an authentic OEM replacement part that is directly sourced from the manufacturer. It is sold as an individual product. The carburetor is designed to fit generators and wood chippers created by Briggs & Stratton, Craftsman, Simplicity, and Tecumseh.

This genuine OEM replacement idle restrictor screw regulates how far the throttle cable can travel in lawn mower or snowblower engine. The throttle cable regulates the engine's speed, fuel consumption, and blade or auger turning speed. If the throttle cable travels out too far, the engine will begin guzzling fuel, causing it to run inefficiently. Therefore, manufacturers install this screw to help regulate the throttle cable. The best time to replace an idle restrictor screw is when making repairs to the throttle. These parts are installed together by the manufacturer so they experience similar aging and wear and tear. These screws can become stripped or corrode into their holes. Should this happen, a mechanic will have to pull the screw out and re-drill the hole. For home repairs, use a socket wrench set and a pair of pliers to access the old idle restrictor screw. This screw is a high-quality replacement part for Toro, Husqvarna, and Tecumseh engines. It was sourced from the original manufacturer and ships without any additional hardware.

This is a nozzle tube that is used in the carburetor of many types of lawn and garden equipment. The nozzle tube fits into the primary body of the carburetor bowl and then passes through to the plastic float. The nozzle tube is the component that determines the right amount of fuel that should move into the engine. It is responsible for preventing air leaks and turning oil into a vapor that can be used in lawn and garden equipment.If there is an air leak in the engine of the machine, it could be caused by the nozzle tube. In this case, it needs to be replaced. Depending on how bad the leak is, the equipment could operate at much lower power than normal. Before replacing the nozzle, the tool should be placed on a surface and the spark plug wire should be disconnected.This nozzle tube is an authentic OEM replacement part that is directly sourced from the manufacturer. It is sold as an individual component. Each nozzle tube is designed to fit snowblowers, generators, and wood chippers with small engines from MTD, Cub Cadet, Toro, Briggs & Stratton, Craftsman, and Tecumseh.

This genuine OEM primer bulb and valve repair kit is an identical replacement for certain models of lawn mower engines. The primer bulb is pressed prior to cold starting the engine, usually three times, which sends fuel into the carburetor. This helps the carburetor start more effectively and ensures smoother operation. The primer bulb assembly is exposed to the elements and it is a part that sees a lot of repetitive motion. As a result, it can wear out, become brittle and crack, or experience other failures. In some instances, the primer bulb and valve may be lost in the process of other repairs. Replacing it with a genuine part like this will provide an exact fit. This OEM primer bulb and valve repair kit is manufactured by Tecumseh and is compatible with several of its engines, as well as some engines found in Toro lawn mowers. There are about 20 machines that take this part, which is a complete kit for the primer and valve. The replacement kit includes the primer bulb, seal, plastic valve, and metal spring. It is important to allow the engine to cool completely before replacing this or any other parts. Wear gloves for hand protection.
