I think I understand your question. When I posted how a friend started a Cont flathead by slowly bringing a wire closer and closer to the plug while the starter was cranking, you wouldn't believe the ridiculing I got by all the know it alls on here.
The guy that did this with me explained it as best he could, cause he isn't an electrical neurosurgeon, just a fork lift mechanic. He said a long arc still feels the juice trying to find the highest point- kinda like lightening, when it hits, it is a higher voltage than if it was in contact, so fouling or not, the gap will make a spark and fire if there is gas.
We were dealing with a brand new seemingly dead coil, and that has been fine since that moment too, again, a jolt of higher voltage kicked it into life same time the fouled plug started firing.
Or, there was a guardian angle of Cockshutts behind us, or an invisible space alien feeling sorry for dumb humans, or I just make this $%^t up off the top of my head....
BTW, just hold the wire with insulated pliers, not bare fingers like my friend did.

Today's Featured Article - Ford Part Number Trivia - by Forum Participants. "Replaced by" means the part was superseded. All of my part books date back to 1964 and New Holland have changed some part numbers. They usually put the old Ford part number on the package. I was suppressed when I looked up the part number of the auxiliary drive shaft because for some reason the part number went through a radical change and it lost its "Basic Part Number". Ford part numbers follow the following rules. Most part numbers are in three parts. The middle part is called the ... [Read Article]
