no spark. What's wrong? Ran perfect then no start. Sparks were flying out around the coil, I replaced it with new and no more sparks, but still does not run. Distributor cap old, crusty and worn. Replaced it and rotor with new and still does not run. Guy at store said it must be ignition module. It was cheap, so replaced it with new and still does not run. Tried gas and ether in carb and didn't fire. Definately no spark. Checked plugs. Not fouled. May have been tampered with. Any ideas?
