Pertronix and Vacuum

I just installed a Pertronix module and coil and now the car doesn't like to start as easily as it did. It used to start after one revolution, but now I must crank it 6, 7, or 8 times before it starts. Any ideas?

Also, does anyone have a diagram that shows where to run the vacuum lines to the distributor? On the forward port I have a line that comes from the forward vacuum distribution block but is also teed into the rear block. The rear port on the distributor runs straight to the forward block. With that setup the rear port is receiving much more vacuum at idle than the forward port, which seems correct to me since the vacuum should only kick in under acceleration.
