That actually is pretty nice Jim - if it weren't a copy of a Wiggers, and thus mentally compared to one, it would be great and I'm sure there's more than a small price difference. Do they make engines based on other Wiggers models?
Larry, I bought this one off eBay used. I haven't been able to find a lot of information about them.
I did locate this link from the 'maker' in India and they have two other models (further down the page) that they produce. I do wish they accepted PayPal though -
