Briggs Stratton 797139 Float Needle Valve

Product Description

The BRIGGS STRATTON 797139 is a float needle valve designed as a direct OEM replacement component for small engine carburetors. This part controls fuel flow into the carburetor float bowl by seating against the inlet seat to regulate the fuel level during engine operation. It is a critical wear item in carburetor service and rebuild work, typically replaced when an engine exhibits flooding, fuel overflow, or difficulty maintaining a stable idle. Small engine technicians and outdoor power equipment service shops are the primary installers of this component.

The 797139 float needle valve is used in carburetor service applications on small gasoline engines found in lawn mowers, riding tractors, and other outdoor power equipment that use BRIGGS STRATTON engines. It is well suited to carburetor rebuild and overhaul work where the original needle or seat has worn, corroded, or failed to seal properly, resulting in fuel management issues.

Installation Notes

Installation is typically performed by a small engine technician during carburetor service or rebuild. Shut off the fuel supply valve and relieve any residual fuel pressure before disassembling the carburetor. Handle the needle tip carefully to avoid damage to the seating surface, as a nicked or bent tip will result in continued fuel leaks. Follow the engine manufacturer's service documentation for torque and reassembly sequences.
