I picked this lovely Sunbeam base up from fellow member Kye, pre Victa days and I believe this would be a four stroke base unless the two stroke model used the same base but with an adapter plate.
Would anyone have some pics of the four stroke machine other than the brochure one which shows little of the engine, the VK40 Kirby engine was fitted using an additional dress cowl similar to the two stroke model pictured.
