Description
Overview:
This is a genuine Honda governor spring for GXV-series vertical‐shaft engines, used to control and stabilise engine speed under varying loads.

It is designed for Honda GXV390 (including GJAA variants) and selected GXV340 engines for a reliable, direct fit. Typical applications include professional and domestic lawn and turf equipment that rely on steady engine speed for clean cutting and safe operation.
