When you used the flat primary, did you try lowering the bottom of
the secondary somewhat below the primary (maybe a couple of inches
below if needed)?  This should have tightened the coupling and restored the 
proper spark output I would think.  (The possibility of primary to secondary 
increases however, so I don't really recommend this approach, but it 
never-the-less makes a good test.)

I don't think a person can ever think *too much*    :)   The approach
of thinking, experimenting, and discussing ideas with others is a winning
combo.  The great wealth of info from the smart minds on this list is
of inestimable value.
