Ok so I jsut cranked up 1 of my Babe bee's after trying furiously to get it going. After few spins and lil N/V adjustments it burts into life roaring and causing all the neighborhood dogs to howl.

 After bout 30 seconds or so I noticed the N/V tunring on its own clockwise and the motor started to sputter a little until I moved it back and it was singing away again and then it moved again and finally shutoff.

 ANy idea as to why or what could cause this?

And if you can't find a spring, a peice of small tubing will do the same thing.
