This Stuart 10H is machined from genuine Stuart iron castings probably from the 1960′s or 1970′s. I bought the castings in 1988 from a fellow in San Diego who had bought them some years before. I machined and finished the engine about 20 years ago. It has mostly sat on a shelf since then. The engine turns over very smoothly and will run on very little pressure. It has a 3/4″ bore and a 3″ flywheel. Overall dimensions, with the base, are about 8″ long x 5″ wide x 4.5 tall.
