The Nova-1 was a 40’s era Dutch design which was documented and built by a group of engine builders called the “Motor Boys”. The drawings were included in a book of plans sold through the AMA in the United States.I machined one engine approx 16 or do years ago. It was a good running engine on traditional diesel fuel (1/3 ether/kerosene/oil).…Very tall engine. Longish strike but mainly due to the long connecting rod.
