From what I can find out the basic advance is:
0 degress @ 650 rpm
7 degress @ 1345 rpm
10 degress @2100rpm
The vaccum advance adds an extra 10 degress @ 10" of vaccum.
A stock Model A needs about 20 degress, my motor with the modifications, CAM, head, valves etc. would probably need more.
Anyone got any information on this?
Thanks

This is from a man who knows nothing....... But, it sounds like if you set the initial advance like 10-15 and use the vacuum that you would get what you needed.
