Dura Force spark problem

I have a model 10525, #8906368 Gold series which I bought brand new in 1999. It's my 3rd or 4th LB and It's a beast. I love it...except. This year when I pulled the rope, I got nothing. I completely rebuilt the carb last year and it was awesome. Now I am not seeing any spark. I also have a silver series Dura force which I bought as sort of a backup. It also took a dump. But I robbed the ignition pack and tried it on the Gold and still got nothing. Then I got a Chinese made ignition pack from Ebay. Nothing. The Kill wire looks good. The kill switch seems to me to be working correctly just looking at it. But the little plastic kill switch stop is missing the little nub at the top. The other backup LB kill-switch was still intact, so I switched them. Still no spart that I can see when I ground the plug against the engine and turn the flywheel.

I'm getting balder by the day from pulling out my hair. Please help me save what's left! :confused2:

Any suggestions from you experts?

Thanks a lot guys!
