The Lucas has always been better. Many people are now using the Alden
modified distributor (where did "dizzy" come from anyway?) or the Petronix
electronic modification. You want to do some research first before you start
ordering parts. First, what advance curve do you want? The weights in the
distributor which control the mechanical advance are removable and different
weights can be substituted for different curves.
Many people will tell you to use a vacuum advance for street applications,
but remember, the Mini Cooper came with a centrifigul-only advance. The
vacuum advance should run to the manifold, but be sure to check that the
diaghram in the advance is in good shape. The simple test is to stick the
end of the advance that connects to the vacuum line into your mouth and suck
on it (insert your own joke here). The little arm should pull into the body
of the mechanism and stay there as long as you are applying vacuum.
Also, you need to check the shaft to make sure it isn't bent. Just check the
point gap on all four cam lobes once you haves set the distributor up. You
should see some minor differences from lobe to lobe. That is why there is a
14 to 16 thou range in the spec books. The closest lobe should be no more
than 2 thou closer than the furthest lobe. Any more and the shaft is bent
too far to use.
Good Luck
