I am looking for a stand alone ignition system to use with my mechanical fuel injection.
Does anybody have an experience with this system. I understand that all it
needs is power and a input from a trigger wheel. The units and the trigger
wheels can be found in junk yards I am sure. I can also make a trigger wheel
with a plasma cutter.

This is stuff from Google.
