OK, I dried out the saw completely....pulled the plug, pulled it over numerous times, let it sit over night with the plug out at BDC. Reinstalled the plug and went through the starting sequence and no fire on more than 30 pulls on a saw that was until SUDDENLY a 1-2 puller.
It was after this that I dried it out again, gave it a couple of drops of gas and it still wouldn't fire. It was then that I did hit it with a small amount of ether..:msp_w00t:..yes, yes I did it's my saw and I can do that...anyway it still did not fire...
The saw was fueled off of the same 2 gallon fuel jug of non-ethanol high octane 50:1 premix with Amsoil Dominator 2x prior to this fill that same day so I don't believe fuel is an issue.
It is the SUDDEN failure that is making me think it's ignition related, yes it has spark but it may not be enough or at the right time....

when you did this...did you use the choke?
