Carburetor runs on choke and no fuel squirting at nozzles

[ellisjay2]

Have been having this problem I think of fuel starvation. On a cold start full choke engine will hit and run, until it begins to warm up and with manual choke, once I move choke open will die.Will idle at half choke. I also noticed fuel isn't squirting out nozzles in carb. Have a clear filter before carb half full of fuel, pressure gauge also showing 6psi of pressure. The carb is a Holley 4150 double pumper. Before this I had a flooding issue in both secondary and primary as fuel flooded out air vents, I replaced both needle and seats and flooding problem ceased. I adjusted both floats to where fuel is seen just below sight plugs as you shake engine and get trickle of flow....if I raise primary float anymore, flooding out air primary vent reoccurs. When opening air throttle it starves immediately. It sounds as if I need to pull carb and do some cleaning and break off fuel bowls...clean out venturies...

....This just started recently....sounds as if trash or so is getting involved..clear filter does show brownish particles...
