3/4" for your spark gap does seem a bit wide.  You must have a good capacitor
to hold up with a gap that wide.  I think my safety gaps are set at about
1/2".  The widest gap I ever used with the neons was about .150" - using a
cylindrical gap with each individual gap at about .030".  Now with the pole
pig I am using a rotary gap in series with the static gap.  The safety gap
only fires when I get a strike down into the primary.
