Product Overview
When a V-twin mower surges at governed speed, falls flat under deck load, or will not restart after sitting with ethanol fuel, the main circuits or inlet system may be restricted. This kit replaces the carburetor assembly after fuel delivery, ignition, and intake leaks are ruled out.
Use the complete engine model, type, and code. Similar-looking Briggs V-twin carburetors can differ in jetting, solenoid, choke, and linkage details.
