The Brazilian manufactured RIOMAR engine. This engine looks very similar to the West Bend 610/820 engine. The shroud usually are painted red and the spark plug comes straight out from the center of the cylinder head versus West Bend's angled to the side from it's hemispherical cylinder head. In use since the early 1960s.
