I picked up an old 14" monitor at Goodwill for $2.00. It worked. I
removed the flyback transformer for HV experimentation.
I hooked up a 9 volt battery on the input and setup a small gap
between the HV output and hv return. I though a momentary 9v pulse
would produce an observeable spark on the output. No such luck.
Any suggests?

I am not a TV repair expert, but the flyback transformer may be
powered from a higher voltage supply. 9v may be producing a few
thousand volts but not enough to make a spark. You need around 10kV to
see a good spark.
Other things I remember about flyback transformers:
They are very low output power.
They are self resonant so they are not just a simple transformer.
The circuits for creating your HV supplies using old flyback
transformers always start by winding a new primary and do not use the
primary on the coil.
Try searching the web for high voltage and flyback. There are a lot of
circuits out there that people have built.
