Sears Engine Carburetor

The comprehensive carburetor kit contains all of the parts and components necessary to make almost any repair to a carburetor on the makes and models mentioned. A carburetor is a part that mixes air and fuel within any combustion engine. Without adequate or ideal air to fuel mixtures, the engine may misfire or run poorly. It is not unusual for older or heavily used engines to need carburetor repairs. This is a carburetor kit for lawn tractors, lawnmowers, and small engines made by Tecumseh, Toro, Lawn-Boy, Cub Cadet, and MTD, among others. It ships individually.

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.

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.

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.

This is a main nozzle tube replacement for use with a range of different types of outdoor equipment and small engines. Another name for the main nozzle tube is the fuel jet. The fuel will turn into a vapor and then travel through the main nozzle in a vacuum process. This draws the air into the Venturi pipe. The main nozzle tube is made from plastic, and it can eventually start to break down and wear away. When this happens, it will no longer be efficient. Owners might find that the engine is not running smoothly, or that it is difficult to start the engine. Replacing this element of the system could be what is needed. This is a genuine OEM main nozzle tube replacement. It is sold individually and works for various models of lawn mower, snowblower, tiller, pressure washer, generator, log splitter, wood chipper, and other small engines. Compatible brands include MTD, Toro, Cub Cadet, Lawn-Boy, Craftsman, and Briggs & Stratton. Owners should always ensure they are getting the correct replacement for their make and model.
