I think 1 or 2 of your transformers maybe connected the wrong way around, 
if you knwo what I mean, so the peak of the sine wave created from one 
cancels the trough created by the other.... just a thought. Try hooking 2 
in series, not 4, and seeing if you can get an arc with them. If not, try 
flipping the 'polarity'  of the output of one. THen see if you get a bigger 
spark. DO this to the other pair, then put the pairs together, treating 
each pair like a single transformer like before.
