GF40 40cc 4-Stroke Gasoline Engine w. Silencer

O.S. Engine GF40 40cc 4-stroke petrol engine with silencer

The GF40 is O.S.' 40cc 4-stroke petrol engine and complements the 2-stroke GT series. The design features pushrods and a teardrop-shaped rocker cover, a hallmark of O.S.' 4-stroke engines.

The mounting dimensions and the distance to the drive washer are the same as on the 2-stroke GT33, so the engine is easy to swap in. The included F-6040 silencer reduces noise and gives a genuine 4-stroke sound, and the specially developed Walbro carburettor responds quickly and is easy to adjust.
