The two oil fill holes are in the GX series single-cylinder engines. These engines can be mounted many different ways. Honda has provided two filler holes and two drain plugs to ensure that one of each is accessible.

For the filler holes, the grey cap has the dipstick. The black cap is a plug. The GC engines only have one plug.

The engines are covered by the engine manufacturer. The owner is responsible for registering the engine with the appropriate engine manufacturer or distributor, as outlined in the Engine Owner’s Manual which accompanied your Wallenstein product. All warranty work must be done by one of the engine manufacturer’s approved servicing dealers.

Modern engines are designed to run most efficiently at full governed RPM. Therefore, our engine-powered equipment is designed to run most efficiently at the same RPM. Running engine-powered equipment at less than full throttle is counterproductive. Engines usually require a moment to warm up enough to accept full throttle and load.

The engine versions we use do not have a reduction gearbox. However, most of the engine models we use are available with one. Honda mentions them in the owner’s manuals because the manuals cover all versions of each engine.
