Petronix Electronic Ignition Any Good?

I keep pluging away on this, just for the hell of it , I pulled all 8 plugs, Ngk gr4gp , plugs, ALL 8 WHERE ALL SCOOTED UP WITH CARBON, I had cleaned prior because they where gas soaked, now they where all scooted up. I am ordering a new set of Champion rn12yc, after cleaning and regapping my plugs to .35, I tried to restart car, it fired up and I was able to rev up the engine , it seemed to clear up , then it popped thought the carb. maybe timing is to retarded?? Will wait for the fresh plugs and adjust the timing more advanced.
