The finest miniature engines in the world

Let me introduce the Little Jon 0.1 diesel engine. The 3 piece crank case was machined from bar stock and sand blasted. My son Jon Valentine produced 5 of these engines. The cylinder and spinner were anodized in purple. This engine turned out to be a great runner.
