[Mgb-v8] Carb to dizzy connection

[Paul Hunt]

I quite agree, they only really differ at idle, in all usual driving
conditions they are the same (see my tests at
http://www.mgb-stuff.org.uk/wn_ignitionframe.htm and click on 'Vacuum_Advance
- Carb_vs_Manifold').  Many people get hung-up on their being different
distributors for manifold source and carb source.  It's quite true that North
American engines and distributors changed when the source changed, but they
changed just about every year as the factory were continually chasing the
moving target of emissions levels!  UK cars didn't change until much later on,
but kept the same engine and distributor when they did, in fact for the whole
of rubber bumper production.

  Most distributors can be set up either way if you know what you are setting
  out to do. Some engines may prefer one over the other. Usually these is not
  much difference either way once set up properly. They will both the job on
  the street by aiding fuel economy.
