Thank you Tinkicker.  Now everything in the world makes sense! 

Here's an instructional video on repairing CDI's to guide folks that have "exceptional" knowledge of ignitions and repairs...  (I found it on the Internet so it must be accurate)

Whatever is in ethanol fuel, seems to earth out the centre electrode, and prevents start, until either a new plug is fitted, or the plug is heated with a blowlamp?

This I would guess is one of the reasons why the majority of people running businesses, that use 2T powered equipment, dont use ethanol type fuels?

Ethanol is corrosive to metals like aluminum, hard on rubber parts like the critical little diaphragms in most 2T lawn equipment "pumper carbs".  It also doesn't store well and can absorb a lot of water.  Lots of reasons not to use it in lawn equipment or older machines if you have a choice. 

(On a side note, ethanol absolutely annihilates old gasoline deposits....  I've had a couple of old tanks with a thick layer of rock hard sludge in the bottom...  filling the tank with E85 dissolves the crud in a few days and both tanks came out spotless.) 

I don't know that I've fouled a plug in one of my two strokes in 15 years and ethanol mix gasoline is pretty much all I can get without buying expensive specialty fuels.  Been on many group rides and I don't remember anyone fouling a plug.  I can't say that was true before ethanol fuels...  plug fouling was a much more common occurrence back then.

Significantly increased plug fouling from ethanol fuel?  That might be more folklore than fact. 

 

The coil had some tape around the plug boot, and it was a little loose where the wire goes into the coil, I think it was a mix of the wire and plug, but atleast I got it to start easily

Congratulations!

That kind of problem can be tricky and maddening to figure out. Good job.
