No Spark/Bad Ground?

[Pelikan]

Hey guys.   Done a lot of work on my bike lately.  Major prob was stuck needles/no fuel to the carbs but I got that fixed and verified gas was going to carbs and into cylinders, which it is.  Bike just turns and turns though.  Pulled the plug and no spark, but if I touch the body of the plug to a piece of metal I get spark.

The bike ran on starter fluid (fired) before I pulled the carbs so maybe it's possible I didn't connect something?  Or maybe the ground is bad?  Where should I start?

EDIT:  I used starting fluid this time as well.  Is it possible since the carbs had gas that it just got badly flooded?  Will letting it sit overnight help?
