HI - i have set up my 360 to ground run in the garage at home (see pic). It was running fine with the points system but then i changed over to a rebuilt electronic dizzy, new Orange ECU and MSD Blaster2 coil. Now it won't run. It backfires up through the carby all the time and the ballast resister (1.25ohm that came with the Blaster coil) gets very hot very quick and starts crackling and smoking after about 15 secs. Unfortunately it won't run for me to check the timing. I have made sure the system is wired up correctly.
As teh cam is less than mild i have closed up all the vacuum ports, no vacuum advance yet and no PCV- all closed, to give max vacuum.
However i noticed that the elec dizzy rotor position compared to the points dizzy rotor position is slightly turned more clockwise- ie, it is a few degrees further on. BUt this shouldn't matter as its all relative to the dizzy housing. Should the ballast get this hot so quick when ignition is first turned on? I have tried various initial timing settings- always just backfires after firing and dies. I have another new dizzy and used ECU- i might start swapping things around to eliminate.
