The "Etek RT" motor isn't really a B&S Etek at all, it's a re-badged Mars ME0709 that's misusing (in my view) a Briggs and Stratton registered trademark. You can buy these motors direct from Mars Electric LLC, who are very helpful (I have one of them in my motorbike project) for less than this reseller sells the re-badged ones.
Mars Electric is run by one of the guys who worked for B&S on the Etek project, so has a good understanding of the technology. When B&S pulled the plug on Etek production John Fiorenza set up Mars to make two similar motors, the ME0708, which is similar to the original Etek and the ME0709 which is bigger and has a lower Kv. Mars also make a brushless version, similar to the original Etek in power.
One question I've been pondering is the situation with regard to technology licensing and patents. The B&S Etek was made under licence from Cedric Lynch's patent, as I understand it. I have no idea if the Mars motors use the same Lynch technology and whether or not they are licensed by Cedric (or the Lynch Motor Co) if they do. I do know that the Mars motors are made in China, although I have to say that I've been very happy with the quality of mine.
Service from Mars is outstandingly good, nothing is too much trouble. My motor was slightly damaged in shipping and John sent the new parts out immediately, free of charge, by priority shipping.
