Man you have all the luck don't you!
If your ignitor is getting everything it needs but no spark it might have gone bad. I have had one go bad spontaneously, one other I fried with welding. SO yes they can go bad.
Other things to check are the pick up coil in the distributor and those pick up wires, I have had those get crusty enough to not work. It sounds like you eliminated those already though.
Want me to see if I have an ignitor for you in the shed?
Post up a photo of the style you have.
