Me, too. I've written Bob Kramer at DL USA about this. I have had three of these, now own two, and they work very well; no carburetor issues at all. The "newest" version, that I'm aware of, is the standoffs and thicker mounting lugs version, with some minor hub improvements. Performance is identical to earlier ones that I had.

The newest engine (one week old) has the WT - 664A carb on it.
