The finest miniature engines in the world

Flat Four

Here is a 3.2 ccm 4 cylinder opposed twin glow engine we manufactured back in 1986.

The engine runs very smooth and powerful. It also idles excellent with the 2 needle carburetor. The 2 piece crank case was machined from bar stock and is mounted with a rear mount. The crank shaft is in one piece and the connecting rods are divided and assembled with two miniature screws.
