Holley/Demon Carb stumble

I understand.
I don't wish to undermine anyone else's suggestions..
Just a thought, beings the specific gravity of fuel doesn't change with altitude (sarcasm) but air does (you're at 9000ft right?)
I'm wondering if your issue couldn't be resolved just by simply reducing the low bleed by a couple sizes, in an attempt to 'bring in' the fuel at the booster sooner? It might be worth trying if you have some on hand, even if it is to prove this wrong.
just a thought, don't kill the messenger..

No messenger killing here.:elmer::lol: I appreciate all appinions
First i have air bleed but only for the proform/holley. The Demon carb has much smaller brass inserts. found a small enough screwdriver to remove the air jet.
With my reading glasses and a Magnifying glass I couldn't read any numbers on it and it look like it had a letter on it. Don't know but i don't have any air bleed for the demon except whats already in there.

Maybe i could find some fine small wire and put that in there for temp to see.........bend a Z so it can't fall in.............
When you say the low bleed your taking about the ones in the main body right?.....High Speed bleed? still learning.
