Re: "B" Distributor timing with an "A" front cover
Patrick, if my feeble brain has finally got this, this should be the case. With the "B" distributor and an "A" cover, if you fully retard the point plate position as indicated on the adjustment on the distributor, and time the ignition the same as you would with an "A" distributor, you have the initial timing at TDC, move the "B" plate adjustment to its center, you end up with 9.5* advance as initial timing.
Critics, please comment, am I correct? This, to me, is a good starting point. Take the distributor and put it on the Sun machine and you can plot the advance to RPM
