The unit was intermittently hard to start. It would crank with no problem just wouldn't start. While checking spark I noticed silver rub marks on the tops of the plug wires. The foil heat shield of the hood was coming loose and sitting on the wires. I fixed that but the engine still needs to cycle 4 to 5 time during start up before any spark is seen. Is this normal? The coil, wires, plugs, cap/rotor and regulator are all about 9 months old.
