Parts for Tecumseh TYPE 670-36: Caburetor No. 631312 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.
