So Wisconsin sold the Robin to Teledyne, who now sold the Robin to Punsun in China. Well well. Welcome to the world of the Red Giant.

The Wisconsin Robin was one of the most relaible single cylinder industrial engines ever produced, then Teledyne got it, changed the block from Cast Iron to Aluminum, and it still was a great design. Wonder what mods the Chinese made?

Wonder what it looks like now? The insides I mean? Of course nothing will ever beat a OMC singe cylinder air cooled gasoline motor (Made in Lincoln Nebraska, also known as Cushman).

.83 liters eh? Let's see, 61 cubic inches to a liter, hmmmm....makes it about a 830cc V twin. Cool. 20 hp should make it last long time sailor boy.
