No spark- what am I missing?

Hows the end play on the dizzy shaft?

My money is on a bad condensor, you will get zero spark with a bad condensor and I've had them be bad new right out of the package swap it and I bet she'll fire off
You can just disconnect the condensor temporarily to test to see if it is shorted; just don't run it long like that or it will burn the points.

A shorted condensor should show 0 dwell angle..... but it won't hurt to check.
