Jim, There are many different typs of CD ignition, but the prevailing problem for many is the opposite of standard style systems. Super-fast rise time; but super-short duration! Many CD systems require a LARGE gap simply to be sure the spark might hit something and get the fire started. Multi-spark discharge systems are usually CD of some sort. If not the coil current required is super high OR a dc to dc voltage stepup system is required to allow the coil to fire multiple times per ignition event. I am supprised Lynn could run such a small gap with success. Lynn was that small gap WITH a MSD system?
