B40 SS90 ignition advance

[berniej]

Just finished cleaning and rebuilding the distributor and, as per RR singles book, was checking for the advance stamping on the bobweight platform.

Mine shows 10 degrees although RR states "B44 and B50 12 degrees, all others 15 degrees except energy transfer models which are 5 degrees".

Is 10 degrees correct for the SS90 and what is the static timing setup please?

Thanks,
Bernie

The distributors changed advance range. The service sheet from January 1963 explains and also gives static timing.

Brilliant! Thanks Julian.
