84 gt350 mostly stock. sometime it will just spin over but will not fire hot or cold engine does not matter. Its getting fuel but install new carb last week anyway. ok where to start?? I've replaced ignition switch three differnet ones, two different duraspark ignition boxes,two different coils, rewired wires from duraspark box to distributor they had raw places in them. I can drive it somewhere and switch it off like go in a store and come back and it will not start, but it had did this cold to at home. with key switch on it has power to the positive side of the coil and to the duarspark box. But if I disconnect the two coil wires positive and negative and reconnect them it will fire right up. anyone have any ideas??
