I am restoring a 1959 6 Cyl. Graymarine Model 116. To check the centrifugal advance of the distributor, I am searching for the advance curve data. The distributor is an Autolite IAY 4013A-3P.
I already installed the distributor on a test stand and found out that the centrifugal advance ends at 8�(Distributor Degree) at 750 RPM (Distributor RPM). This RPM seems to be very low. Has anybody data regarding ignitions of these days? Any help would be very welcome.

Thanks
Roman
