I have a spark that jumps from the center terminal on the ignition coil ro both of the screw terminals on each side. Is this going to be a new coil? or new cable? I made it stop last time by cleaning everything...

I dont think things have changed that much, from my auto shop days. I learned the spark takes the path of least resistance, therefore bad wires, cap(s) rotor or plugs. The arcing into the coil(s) can not help their life cycle.
