The following article is my personal opinion. I have tried to be fair, honest, & fully inform you.
Here is a URL for Tom Cutter's now rather old article on dual plugging. While it has some errors & things that need updating, this may be useful if you are interested in more of the theory & background: http://rubberchickenracinggarage.com/Downloads/TomCutterDualPlugIgnition.pdf
Please refer to other articles on my website, dealing with the pulse-air system and ignition system, etc.
