So for the fun of it I'll just set to 14 again, plug the advance and see how she goes.
If it's running good at WOT, i might just try to restrict the vacuum
If all that doesn't work the Mallory will go in, which will hapopen sooner or later anyway. I'm just too lazy to hook up the box and coil and whatever cablecrap is with it ...
