Thanks for the advice, Merv & Goran.
I can try to close the gap on the plugs and test.
If I do need stronger sparks, do I need to simply change to a different coil - what kind would you suggest? For the beginner, how would an external ignition system help? I'm particularly curious about other EFI system (like SDDS) that also uses wasted spark (like Megasquirt) - how could they produce a stronger spark?
