Yebbut the spark intensity is down to the coil's output voltage and the
dwell period, not just the points that are switching it. In the case of the
mallory, the twin points are definitely an advantage over a single-points
rover dizzy, by allowing a longer dwell period for the coil to "charge up"
and the elimination of high-rpm points bounce. However, both these points
(no pun intended!) are made obsolete with an electronic dizzy, which has a
longer dwell time and higher rpm (switching) limit than any points dizzy.
A Lucas DLM8 dizzy, correctly set up with sound condition cap, rotor arm,
leads, plugs and coil is as good as any mallory in my opinion,
notwithstanding the mallory's ability to alter the total advance. The lucas
unit can have the total advance altered as well, just not as simply as
turning a screw, and both types need to come apart to replace springs if
altering the advance rates. Added bonus of the lucas one is the ability to
obtain spares easily, very handy if you suffer a breakdown somewhere.
Just my personal thoughts.
Badger.
