Hei conversion troubleshooting

I think I just figured it out. Rotor phasing in my BRAND NEW distributor. With no advance in, the rotor is just barely lining up with the lead edge of the cap contact. As advance comes in, it gets farther away. With full advance in, its probably sitting directly in between cap contacts. My understand is that it is supposed to be on the trailing edge of the contact at base advance setting, so that as advance comes in it sweeps across the contact.
