If you have not taken time to read the links I posted I would take the time to read them. I think this sounds like a timing issue.
Are you sure it is a B cover? If it was a B cover drilled for Model A, a replacement, then you would only be getting approx 7 degrees advance.

The B distributor has not 7 but 12-13 degrees of advance from the initial 19 degrees. A rusty and worn B distributor will tend to give less advance.
