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.

This is a genuine throttle return spring used on select small engines. The throttle return spring is part of the throttle system. It is attached to the throttle cable and the throttle body or carburetor, and is responsible for pushing the throttle closed when the gas is released and opening the throttle when the throttle trigger is engaged. If the spring is faulty, the throttle will not be able to open and close properly. This can affect the machine's ability to operate and even prevent it from operating at all if the throttle remains closed and no power can get through. A replacement should be done as soon as possible to prevent further damage to the engine. This genuine OEM throttle return spring is manufactured by Tecumseh, and compatible with machines from Toro, Husqvarna, MTD, Lawn Boy, and Tecumseh. There are over 150 models that can use this replacement part. It is made of durable metal and sold as an individual part. This throttle return spring is a simple replacement that should only take a few minutes. Be sure to use care when replacing the spring because it can be susceptible to damage under excessive pressure or strain.

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.
