ronic ignitions that I have used (or am using), none will fire a fouled plug.
In fact the design of Ford Duraspark system will not fire with fouled plugs at all.
When a plug is completely fouled it is completely coated and insulated. Current no longer can find a way to ground itself through the plug and stops flowing. No spark.
I use the Eastwood plug blasted on my co



I think current flows too good on fouled plugs, upon the surface, and doesn't bother to jump the air gap. fouled plugs are too conductive, not less.
Beware those plug cleaners, one missed piece of SiC media loose in an engine can score a cyllinder like crazy.
