PVL Ignition Troubleshooting (1200 Carbureted Engines)
Verify spark plugs are RESISTOR TYPE!
If the battery voltage is low, cranking rpm will be down. The ignition system may show weak spark with
a plug out of the cylinder, but not spark under compression or it may show no spark at all. Install a charger
on the battery to ensure good cranking rpm.
Verify the firing order. If the plug leads are all the same length, trim them so they can only be installed
on the correct cylinder.
Read through the entire procedure before proceeding. Some steps are repeated. The correct sequence
depends on the readings obtained in step one (1).
