Breakin it in

I took the car out for a spin, since the Weber and the MSD ignition system is still new. I'm in the process of breaking them in, however there is white exhaust gases coming from the muffler. This indicates a lean mixture, however @ 3000+ RPM a slight black smoke appears, the engine happily screams up to 6000 RPM. With the tuning to the Weber and the vaccumm advance hooked up I can now go WOT and the car responds very well.
