So when you lined up the dots with the cam gear at 6 and the crank gear at 12, did you know that's not #1 tdc compression. It's #1 tdc exhaust.. To get to #1 tdc compression you rotate the crank once which puts the cam gear dot at 12 and the crank gear at 12.
So with that said you're likely firing 180 degrees off.
Easiest to just point the rotor at #1, lift the dizzy and rotate the rotor around to point at #6. Advance it a little and it should fire right up.

And why haven't you switched to an hei yet?
