Parts for Briggs & Stratton 128T02-0123-B2: Carburetor, Fuel Supply Parts

Fix poor engine performance and hard starting with this carburetor overhaul kit. Restores proper fuel mixture for lawn mower and trimmer engines.

This carburetor is built to mix gas and oil before the mixture moves into the engine. It is a single-cylinder carburetor that has an auto-choke system and requires regular maintenance. Replacing the air filter, changing oil, and adding fuel stabilizer can increase the life of the engine when using this carburetor. Carburetor issues can be caused by blockages of dirt, fuel, and debris. If an engine won’t start and the fuel tank is full, testing the carburetor can be done by taking out the air filter and pouring a tablespoon of fuel into the carburetor. Pull the starter rope and see if the engine starts but then dies soon after. If this is the case, the carburetor is likely the issue and will need to be replaced. It’s recommended to replace the gaskets at the same time to ensure an airtight seal. This is an authentic OEM replacement part for lawn and garden tool engines. It’s compatible with lawnmowers from Toro and Briggs & Stratton. It comes as an individual item with the carburetor, a gasket, and a rubber O-ring. A screwdriver will also be needed to make a replacement.
