It may seem odd, but I've just picked up a new one of these (been sitting on a shelf for a while).

Anyway, the information provided simply says go to www.mytsn.com to get info on the motor, but that web site doesn't seem to exist anymore.

Does anyone have any reference material on this motor? Has the info at mytsn.com been moved somewhere else? Is this an OEM motor from another manufacturer?

Particularly looking for base carb settings and any guidance on running-in, plugs etc.

Phil.
