Holley/Demon Carb stumble
I was running a mighty demon 825 for awhile and frankly got “lost” in tuning it. I took a step back and went back to the stock setting and started over. Like stated above I would go back to the original squirter. It is probably just slamming raw fuel onto the bottom of the intake plenum and puddling. Getting it warm helps it evaporate, so the squirter could not have “fixed” it for a day. Have you tried to delay the pump shot a bit? Looser converter lets it gain rpm easier so it doesn’t need the pump shot to cover the transition until it has enough air velocity to pull fuel.
