Re: Purpose of dual points?
The only dual points system I've worked on is on my 1978 Suzuki Motorcycles. Both are four cylinders. They use a lost spark system. Each time a set of points opens you get spark in two cylinders; one at the top of the compression stroke, which fires; the other at the top of the exhaust stroke...which does nothing.
It is a surprisingly simple and efficient system.
