I need to ask a few questions and please do not think I am insulting you.
How much gas is in tank?
Is the gas good gas and not with water in it? Can you take any gas from the hose into a clear container and wait a minute and see if separation occurs?
Can you see gas squirt into carburetor when you pull on the accelerator cable or push the lever in on the carb? If you can see it..it is going into the intake and .most likely bad gas.
Lastly and another problem area is the fuel jet inside the carb is stuck or has an obstruction such as goo from bad gas?
This gives you some ideas on what to look for and thanks for using FixYa.
Ok as I said before try to see if gas is squirting into the carb when you hit the gas pedal or push the lever at the end of your accelerator cable attached to your carb. Take the aii breather/filter off again if you haven't and get a flash light and shine down into it while hitting the gas hard and quick . If you do not see any stream of gas then yes the float is stuck closed. You could also have a bad acceleratiion pump(located on the side of the carb and shoots the gas into your carb) but I doubt that cause at least it would idle. So since you are using good gas have replace the pump and filter...and it still will not run unless you feed it yourself then all it can be is the float if you cannot see a small stream of gas shoot into it. Hope this finally gets you going since you have spent a lot of time on it and thanks for using FixYa.

There is a fuel filter in the carburetor where you pull the fuel line off. There is a bigger nut that you will have to take off to get to the filter. If this filter is clean, you should be getting fuel. There is not much to these carbs. It might be safe to pull the carb off and give it a good cleaning. Get some carb cleaner and spray all of the jets out and make sure that there is no debris in the jets. And make sure that the float is operating correctly. If the float is stuck then the carb will not allow any fuel in.

thanks for info.....I am somewhat mechanically inclined but pretty new to carburetor models....how would i know and what are the symptoms of the float sticking.
1984 ford f-150 inline 6, 1 barrel carb. will only crank when pouring gas directly into carb and will run until gas burns off. I am getting strong fuel to carb through fuel pump. If my float is sticking how would i know? PLEASE HELP
thanks for the info! I actually just dropped my tank and changed all rubber fuel lines due to dry rot. The gas i am pouring down my carb is from my tank which is lying on the ground in front of my truck. I hooked a Direct fuel line from my fuel pump to the tank. it is cranking with the gas poured into the carb but will not continue to run with the fuel line attached. this problem all started when fuel began pouring out of a rubber hose in front of the carb. next to the fuel filter. i then took the carb off and somewhat cleaned the inside and made sure the float was not stuck. any info would be great! thanks
