Reply to "Engine misfiring"

Of the three electronic 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 compressor. It works pretty well to clean the plug will little hastle.
