Well, in a standard gap the spacing is close enough to allow a certain 
voltage to jump it.
If the gap is too wide the voltage across the cap goes way up. It can go 
high enough to blast your cap or burninnate your nst windings.
The thing about rotary gaps is that they prevent spark until the electrode 
is close enough.
So the longer the electrodes are out of alignment the higher the voltage 
across the cap. Too slow and the cap gets over volted. This is better 
explained on richie burnets web page. He's got a bunch of great stuff.
Look at this and check out the rest of his site.
