Yep, I tend to agree here. It's also opening up the gap that increases bang 
size, so I wasn't sure why you want to reduce it Brian (unless it's way too 
wide and risking frying caps and NSTs. Also, have you actually tuned it yet, 
ie experimented with moving the primary tap point around? I would expect  
bigger sparks than this, even with the small NST.
