Lawn Mower Carburetor

Welch Plug
Genuine Tecumseh part
By: Tecumseh
Part Number: 631027

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.

Carburetor
Genuine Tecumseh part
By: Tecumseh
Part Number: 631921

This is a genuine OEM carburetor sourced directly from the manufacturer designed for use in tillers and other small engines. The carburetor controls the mixture and gas and air that reaches the engine at different speeds. Regular use for prolonged periods can lead to the carburetor's failure, resulting in a sluggish engine and reduced fuel economy. A buildup of debris in the carburetor can also cause failure due to clogged airways preventing fuel from reaching the engine. Replacing the carburetor will solve these problems and is much less costly than buying entirely new equipment. Replacing the carburetor requires less than hour of work and a screwdriver, socket or wrench set, and clean basin. Remove the spark plug from the engine and drain the fuel into the clean basin. Locate the air filter and remove it. Remove the fuel line and crankcase. Remove the carburetor from the engine. Install the new carburetor. Reinstall the parts in reverse order. Start the engine and test the carburetor. This is a carburetor made of heavy-duty metal and molded plastic parts; it is sold as an individual pre-assembled unit. The carburetor is compatible with tillers and other small engines manufactured by Toro, Tecumseh, Cub Cadet, and Craftsman.

Carburetor Float
Genuine Tecumseh part
By: Tecumseh
Part Number: 632019A

This is a genuine replacement carburetor float designed to work with a range of small engines on lawn mowers, snow throwers, lawn tractors, and other equipment. The carburetor's job is to blend air and fuel to ensure that the engine can operate. A carburetor float helps control the flow of fuel, ensuring the proper level of fuel in the chamber. Carburetor floats are not subject to wear and tear type damage, but they are exposed to caustic gasoline and oxygen, as well as high heat. Over time, they degrade and will need to be replaced. If the engine continually floods and will not remain running, it could be that the carburetor float needs to be replaced. Replacing the carb float will require removing the airbox and cover, the air filter base, the fuel line, and the fuel linkage. Clean the carburetor and then remove the bowl. Remove the damaged float and replace it with a new one. Note that it's recommended to replace the carburetor gaskets at this time, too. This is an OEM replacement carburetor float, and it is sold individually. It works with Tecumseh, Toro, Lawn-Boy, Cub Cadet, MTD, and other brands.

Carburetor
Genuine Tecumseh part
By: Tecumseh
Part Number: 632795A

This is a carburetor. A carburetor mixes fuel and air before delivering it to the engine. The diaphragm helps regulate the amount of fuel that is in this mixture. The gaskets create a seal that keeps unnecessary air out so that the engine works properly.A new carburetor may be needed if the engine is running roughly when it's at idle, if there are engine misfires, or if the equipment hesitates under acceleration. If the engine won't start, if it cuts off while running, if there is excessive smoke during use, or if the equipment revs on its own, the carburetor may 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 carburetor is compatible with engines, chippers, shredders, lawnmowers, and vacuums manufactured by Tecumseh and Craftsman.

Main Nozzle Tube
Genuine Tecumseh part
By: Tecumseh
Part Number: 640019

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.

Carburetor
Genuine Tecumseh part
By: Tecumseh
Part Number: 640084B

This part includes the primer bulb in addition to the carburetor itself. A carburetor mixes fuel and air before delivering it to the engine to produce power.

When there's a slight air leak, the operator may notice engine roughness when it's at idle. A larger air leak will cause the engine to vibrate, misfire, or hesitate under acceleration.It's important to let the engine cool and to drain the gas tank before beginning a replacement of the carburetor. 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 carburetor is used on engines and snowblowers manufactured by Tecumseh, Husqvarna, and Toro.
