I didn't request this engine to be sent to me, it just showed up with a request for evaluation in hopes I would want to distribute them. It didn't pass the visual/tear down inspection, I took a couple measurements then stopped wasting my time without running it. I'm fairly certain it will run similar to the rest of the DLE wannabe engines out there - pretty good, not quite as powerful, with unknown longevity because they (most mfgrs. of DL wannabes) don't do their own endurance testing, they want the customer to do it. So it resides in the corner of my shop with the 8 or 10 others with D-something or other cast or stamped into them that arrived the same way, there is no domestic distribution or support that I'm aware of.

I'm sorry if I sound critical of it but that's what my job is and what was requested of me when it arrived. For my money, right now there is only a couple of Chinese manufacturers that I trust dealing with, their current products are unique in design, powerful, affordable, reliable, well proven, and they have a prominent distribution and support network in the same country I live in.
