Hi Neal,
            Congrats on your first sparks. It sounds as if a serious 
effort is needed to tune your coil properly. Safety gap firing is an 
indication of poor tuning and/or coupling.  Also, adjust coupling if 
racing sparks occur or as best tune point is approached. Your coil 
should peak at some combination of settings.

Regards,
Malcolm
