Trying to start rebuilt engine, spitting through carb

Vacuum lines on carb are all plugged, I haven’t hooked up vacuum advance or power brakes yet.

Idle mixture screws are 1.5 turns out.

I wanted to try advancing my timing more but I am up against the slot on the distributor so I’ll need to adjust the bolt under the distributor, I haven’t tried that yet.

Are there any vacuum ports on the manifold you may have overlooked?
