That is true in that picture the timing is a few degrees retarded, If that is the original woodruff key I’m looking at. Have you seen jaguars page he says a completely different story. Another thing I think should but understood is that setting the magnet back or forward will not affect the CDI linear output. Jaguars sells a CDI that gives a parabolic curve. As the engine rpms go up it retards the timing little by little.
