Genuine replacement carburetor for Honda GX390

This Stens 520-738 carburetor replaces Honda part 16100-zf6-v01 on 13 HP engines. It fits the GX390 platform used in many commercial mowers and power equipment. Mechanics and owners restoring original performance will find the correct fitment.

Direct bolt-on installation with no modifications

The carburetor mounts to the existing intake studs and reuses the original throttle linkage. Common issues include old gasket fragments blocking passages and stale fuel residue in the bowl; clean the tank and lines before fitting. Verify the choke plate moves freely after assembly.

Steady fuel delivery during extended mowing sessions

The venturi and jet sizing match factory calibration so the engine holds governed RPM under continuous load. Float-level consistency prevents surging when the machine works on slopes or thick grass. Long-term reliability depends on clean fuel and regular filter changes.
