Description
The Honda 270cc GX Series OHV commercial-grade engine is designed for the most demanding applications. It is famously reliable, with proven durability and longevity. With an overhead valve design for cooler, fuel-efficient operation and a cast iron cylinder sleeve for longer service life, the Honda GX270 will start easily every time, and give you the power you need to get the job done.
The Honda GX series engines are the choice for commercial-duty air compressors for the home builder, framer, roofer, and countless other outdoor power equipment machines. Other common applications include pressure washers, go-karts, log splitters and chipper/shredders.
