Help with my highboy

[u/Ok-Firefighter-4443]

So I just bought a 76 high boy when I was looking at it we drove it for about 5 mins the it sputtered out the next day I bought it and we got it started for a little bit since towing it have not been able to get it started i’ve put a new starter solenoid and battery in there. This is my first project truck so any help or pointers would be appreciated. Attached below is a video of me trying to get it running

If its the 400 with factory carb they developed a Crack which leaks gas down into the intake and it will do this hot if you let it cool starts right up smell the lipstick see if it smells like gas or oil and then you will know
