Cleanup turns to mess up. Need some help troubleshooting.

I might be tempted to spray a shot of ether down the carb to see if does ANYTHING at all. If not, then I would start thinking electrical or ignition. Ballast resistor? Ignition feed to the coil? A wire bumped loose at the bulkhead connector? You spent a lot of time under the hood to do all this work, is it possible something was knocked loose?
