I had two starts that had a long cranking. On the third start (at the gas station after filling up) she would not start. Towed home.
Sprayed started fluid into carbs No start, not even a stumble. Pulled a spark plug wire and held near block. no spark. Pulled HT lead from dizzy. Had a yellow sparking.
I have cleaned the ground strap from the engine to body.
Not owning the car long or knowing it’s history I then replaced the spark plugs, spark plug wires, dizzy (PerTronix Ignitor II) the coil (Pertronix Flamethrower recommended by Pretronix for the dizzy I bought) and cleaned the block where the dizzy makes contact.
I have 12 volts at coil + and engine turns over smartly.
Still not starting.
