Timed my roadster - now runs worse

[ABento]

I also have a nu rex tool, and had the same issue of how it ran, this was on a BB, but it times the same, just no advance lever, I also used it on an A a few days ago and the way the wrench set it it was no where close to what the book says for setting the cam to where the points are just starting to open, about the only good I see in the tool is to hold the cam in place in case the screw was to turn it.
