Parts for Tecumseh HS50-67119C: Carburetor No. 631923 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 spring clip is a standard part found on many small engines used on outdoor power equipment. This clip is used in the carburetor, where its job is to interact with the carburetor float. This helps engage the inlet needle to allow fuel to flow into the assembly. If this spring clip breaks or becomes detached, the float and inlet needle will not function accordingly. This will affect the fuel and air mixture going to the engine, which could cause performance issues. In severe cases, the engine may not operate at all. Replacing the spring clip is the best solution and should be done as soon as possible. This genuine OEM spring clip is manufactured to strict standards by Tecumseh. It can be used in a number of products from the brand, as well as those from Toro, Cub Cadet, MTD, Husqvarna, and Briggs & Stratton. Compatible machines include snow blowers, lawn mowers, generators, pressure washers, and tillers. There are more than 100 models that can use this replacement part. It is made of durable metal and sold as an individual unit. Be sure to work in a well-ventilated area and drain the fuel system whenever performing engine and carburetor repairs.

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.

A fuel inlet is a connector that allows gasoline from the fuel line of an engine to pass through it into the carburetor. Once in the carburetor, the fuel mixes with air and passes into the cylinder, where it ignites to create power for the engine. Thus, the fuel inlet is attached on the one side the carburetor and to the fuel pipe, or line, on the other. This inlet is used in power tools such as lawn mowers, snowblowers, edgers, pressure washers, chippers, and generators. Periodically, since it is made partially of plastic, the fuel inlet will weather and crack so that it is no longer fuel tight. The main sign to watch out for with fuel inlets is gasoline leakage. This is always a dangerous situation. The user may have to remove the carburetor housing cover to determine whether the leak comes from the fuel line or the inlet valve. It is a good idea to replace each of these pieces at the same time. When choosing a replacement part for the fuel inlet, always use a genuine OEM replacement part like this one. This inlet is compatible with power tools made by Tecumseh, Briggs & Stratton, Toro, MTD, Lawn-Boy, and Cub Cadet.
