FAQ

This carburetor is designed for Briggs & Stratton 550EX, 625EX, 675EX, and 725EXI series engines (140cc, 150cc, and 163cc). It is commonly used on equipment including Husqvarna LC121P and Troy-Bilt TB110, TB200, and B110 lawn mowers.
This unit replaces OEM part numbers 799584, 592361, 594058, 594057, and 594529.
You likely need a replacement if your engine is surging, hunting for idle, hard to start, or running roughly. These issues are often caused by old fuel leaving behind varnish deposits that clog the internal jets and passages of the carburetor, which are too small to be effectively cleaned manually.
Installation is a straightforward task that typically takes 10 to 20 minutes. You will generally need a basic socket set, a screwdriver, and pliers to remove the air cleaner assembly and the fuel line clamp. It is recommended to take a photo of the linkage and fuel line routing before disassembly to ensure everything is reconnected correctly.
Yes. This carburetor is not compatible with fuel containing more than 10% ethanol. Using high-ethanol fuel can degrade the internal components and lead to premature failure. We recommend using fresh, non-ethanol fuel and a fuel stabilizer to extend the life of your new carburetor.
It is a good practice to inspect your air filter and fuel line while performing this repair. If the air filter is dirty or the fuel line shows signs of cracking or hardening, replacing those parts at the same time will ensure your engine runs at peak performance and prevent debris from entering the new carburetor.
