While shopping for a generator a few years back I came across a website called utterpower.com that started infecting brain pretty much instantly. Reading through the site I came to the section on Lister diesel engines and their Indian copies. A short time later there was a couple of crates with strange writing on them in my driveway. It has been one of the best investments I have made over the years, and while it is not a Honda, it is fun to tinker with and even more fun to listen to it run. In this thread here I would like to have a place to share info on the engine and how they work. Below I'll post some useful links and some other cool stuff that I've found over the years. This video is a couple of years old, I have it set up differently now, but it will at least give an idea of what the thing is.
