RE: I'll bet this is more 'distributor advance' info than you wanted...

Mr. F. Thanks.

I got a handle on the dual diaphram setup. Now, next Q. How should the base timing be set, with or without the inner port attached to full manifold vacuum? The outside port could be unhooked as well to set timing, but there should not be a signal there anyway, since the base timing is set at idle. I am guessing both lines should be pulled off, but am not sure of Ford's intentions with the retard (inner) port and base timing calibration.

Thanks all.
This thread, so far...
