Ok, the capacitor has one main advantage in point type distributors and that is
to make the spark happens with more zap by shortening the zap time. The current
available is increased by the shorter spark period. This sets the gas off much
more efficiently. As a bonus, it helps the points last longer by reducing
pitting and burning.
