This 2086cc 7-cylinder radial engine is made of aircooled volkswagen parts.
The (mostly modified) used parts are cilinders, pistons, cilinderheads, pushrods, bearings, valvetrain, oilpump and starter of a 1200 Beetle.
The engine has electronic ignition, fuel pump, and a double Solex 2 x 40mm carburator.
The rest of the needed parts are made by myself.
