Well, after a couple of hours of wire testing (buzz testing etc) I was finally able to track down my sparkless problem.  Seems that when I first started my wiring I was short some of my expensive aviation crimp connections and I used lower quality butt connectors.  Well, one of the cheap ones did not hold the wire in and the two white/white&black CAS wires came out, thus no spark.   I have used very few of these cheaper connectors and have replaced most of the few I have used........hadn't made it to these yet.  Just one more thing I am happy to discover on the ground.
 
Since I knew little if anything about wiring 6 months ago and now I feel pretty confortable, I am amazed at how different the quality is on the cheaper and the the better conectors.  I now even know what to look for and have found some much better quality ones at local hardware stores....even though the ones on the plane all came from aviation specific vendors.
 
The engine still starts inconsistantly....one time easy, then not starting at all until I hold my tounge juuuuust right, or so it seems. It also seems to still be running rich. Which is not suprising since I have not done anything to it since it was not running.  Now that it is running again though, I can start to actually TUNE the  beast. 
 
Thanks for y'all's continued support, insight and wisedom.
 
All the best,
 
Chris
