spark control is (in a nutshell):
sensors in dizzi provide timing signal(s) to ECU - ECU/loom passes on raw timing signals to the ignitor - ECU also generates a spark advance signal based on engine load/temp/speed/etc - ignitor uses both (plus does some dwell control) to work out when to fire the coil.
so, tracing back from that, it could be:
coil
igniter
wiring from ECU to ignitor
wiring from dizzi to ECU
sensors in dizzi
i'd suggest gettin a check-engien light working and seeing if the ECU is sending any error codes to you.
Also - i'd be getting a wiring diagram for the engine and double checking everything.
