Whenever ignition timing is mentioned, I wonder if the poster is aware that the TDC mark on the inertia ring of the harmonic damper is capable of rotating on the elastomeric material that separates the inertia ring from the hub. If that has happened (very common), it will be impossible to set the ignition timing correctly. Please read through this tutorial.....
