Pertronix II users

Update on running issue. where to start!, ok have installed the replacement Ignitor II module in the Pertronix dist. as per the directions. Again there is no ballast inplace.,Replaced the spark plug with new Champion RJ14yc plugs, Car will now start, will run for about 20-30 sec. then start to run rough, and keeps getting worse till it shuts off.[ less then1 min.] , Took of the New Holley carb. thinking it was not getting enough fuel, have a see thought fuel filter at carb. can see it is getting fuel also have a pressure gauge there is at about 6psi, which should be good for a carb. have reinstalled my old Holley which was leaking from the front fuel bowl, replaced that gasket, got fuel bowls filled , car stated seems at first it was going to run as it should', maybe 30-40 sec. started to do the same thing, I opened the fuel gas cap to may sure no vapor lock, on the next try when car was started sprayed carb cleaner all around to check for a vac. leak, next try unhooked the power brake booster, made sure all vac. lines/caps where not leaking , next try, ran a wire from + on coil to battery + to rule out ignition switch/ wiring problem. checked the coil to see if it was getting hot, but avg. room temp. Have a photo of the Champion plugs, the plug outer contact looks blacker then it really is, it does show the cut off, I am not sure if this is a correct heat range plug/firing correctly ?
