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.
Best thing to do is pull the distributor and back the rotor up a tooth. Sounds like it's in one tooth retarded.
