318 Won't Start? And I tested as much as I could I think?

Distributor all the way back to hit the firewall, then pulled forward to align first vane, all with timing index marks at about 10 to 15* advance indicated, and with #1piston at near TDC on the compression stroke.
Wire cap accordingly
Thank you, I will reset that tomorrow any try it again. I'm centered in the distributer rotation currently which did give me a bit of a single fire and backfire with it.
