Turns out the factory mesh was to far, and thats why the spur stripped. And yes, it was running too lean but that isnt what cause the stripping, it was the mesh.
They replaced the spur and realigned the mesh. Also adjusted the lean some and the idle. Ran it for a few mins there and all seemed well.
They were cool about everything, and they didnt charge me for the spur or the labor. They said since you just got this, and this is "factory" set, you dont owe us anything. If it was anything else, most likely.
So now i get to restart the breaking process, er break-in process....
