[Diy_efi] Link for greenfire spark plugs...

I'm speculating here, but is it possible that the
exhaust stroke would create a small vacuum in the
chamber, into which the inflow mixture could then flow
a small amount into the chamber by that vacuum. It
might be enough to stratify the chamber and ignite,
this is a very intersting topic to say the least.

Just fuel for thought.
