FWIW, you're not the only one confused by the warp installation instructions. I installed my warp prop with the skull cap spinner 16 years ago and the instructions about the face plate confused me too.
Thanks Tom. I'm a little worried if I set it too low it may over rev the engine during break-in. Or if I set it too aggressive it may not rev enough to wear it in either.
