July 2006. A friend of mine just traded some items and wound up with this tiny engine which resembles a New Holland. However, it is the tiniest one I have ever seen. He says it has 2" flywheels, about a 7/16" bore and about a 5/8" stroke. It has an ignitor, and runs very well. By contrast, the 'little' New Holland sold by Mike Widmann has 4" flywheels and I thought that was small. So far, we haven't determined the origin of this neat little engine ... oh yeah, it RUNS too! If you know anything about the origin of an engine this size, please let me know.
