Honda GX 390

Garden and grounds machines

The Honda GX390 is a single cylinder, air cooled, petrol industrial engine of about 389cc, producing around 13 horsepower. It is used to power a wide range of equipment such as generators, pressure washers, compressors, pumps and other grounds and construction machinery rather than being a complete machine itself. It is valued for its reliability and widespread parts availability within Honda's GX commercial engine range.

We recognise this model across the auction sites and keep every one we see together.

On a used one

Check that the engine starts easily, runs smoothly without excessive vibration, and that the recoil starter and any electric start function correctly. Look for oil leaks, worn carburettor diaphragms, and confirm the equipment it is fitted to has been well maintained since the engine often outlasts the host machine.
