Cool, thank you for the information. Then it is likely that it came from them. I tried to find som information on that company, but it is not mentioned that much anywhere.
You seam to sitt on allot of nice information on these little engines. Nice to know.
These engines was totally unknown to me just a few month ago. But once I got this little generator, I just love them. Love the craft, and the way they are build. A bit addictive actually.
