On my '56 I ran a jumper wire from ign 2 to ign1 on the switch.

I had the opposite problem. I had no ignition in start. And the truck was hard to start for years before I figured it out. It would finally start when I let the switch go back to on after several failures. Now it fires right up like it's supposed to.
