The factory markings can only be considered as a guidance for initial settings. Ignition timing MUST always be checked after assembly, with engine running and adjusted accordingly.
With bits and pieces replaced over the decades, you can't be sure if the markings even match the 2 components. Especially ignition base plates were replaced in the early years in often vain efforts to get the beasts growling again. Little knowledge and even less experience was the main cause for the marques' horrible reliability reputation at the time.
