Ronald Valentine Engines
The finest miniature engines in the world

Let me introduce the Profi 0.67 glow engine. The crank case was manufactured from bar stock and anodized in gold. Cylinder head and carburetor body were anodized in black. This engine is Schnuerle ported like the original Profi's that my friend Hans Hoernlein manufactured in Voehringen-Germany. Hans was the greatest inspiration to me. He received this engine to his 67th birthday. Only 3 of these engines were manufactured.
