Important Fitment Information

Honda GX340 and GX390 engines were produced in multiple versions with different governor and throttle control components. Compatible 188F / 190F clone engines may also use different linkage shapes and spring lengths depending on the manufacturer and engine configuration.

GX340, GX390, 188F, 190F or engine horsepower alone does not confirm compatibility.

Please verify your original Honda part numbers where applicable and compare the governor rod shape, attachment points and approximate spring / rod lengths with your original components before ordering. For clone engines, physical comparison is especially important.
