Alright AK some sever noob questions coming your way so please bear with me.
Ok got the new gasket from Napa.... way better fit! Thanks as I would've never found that out cz every site says that doesn't fit my truck. I got it to fire up way better. Still wouldn't idle tho. Then remembered I unplugged the PCV and dizzy vac hose. Plugged this back up and then turned the needles to 1.5turns (? Coming later) and now it's tougher too start, some times I get a mist sprayed up thru top of carb.
Noob questions
1. When you say turn 1.5turns... do you mean full screw then down (not over tight just snug) and then back out 1.5 or just barely seat the screw, and then turn in 1.5turns.
It looks like I did the latter on my rebuild. Just did the former today. I think the further out I'm turning the needles the better but I don't know for sure.
2. What should I be messing with first? Idle speed screw on the right side. Choke on the left side or the two needles in the middle?
Again first time working on a carb but trying to learn as much as I can. This truck is going to be built not bought lol
Edit* also watched some mike carburetor parts videos and it looks like my choke pull down should be operating better when I'm trying to start. Will this also kill my engine as soon as I take my foot off the gas? Link to video

2100.....if you are not able to run at 1.5 turns, take it to 2 and try it, then 2.5 until you find you idling point. The 2100/2150's are very simple carbs to work on. Probably the easiest over all actually. Make sure that the metal spring clip is on the seat/needle. The PCV tube on the back of the carb, do you have it running to the right rear of the valve cover?

Yeah pcv is going to rear top of passenger valve cover.
Thanks for sticking with me this far.... I'm still learning lol and will get this damn thing running one way or another.

2100.....are you sucking air anywhere that you can hear when you are running? With the 60227 gasket, you said fit better, which it should, then the top is the same. It almost has to be the rebuild of the carb. Did you soak the carb in true carb cleaner, not he can stuff? You may have to use air and clean the idle ports. Like I said, there isn't much to this carb. If you get the carb apart, would you post a picture of the front bowl with everything in place.
Maybe, try and cap off the PCV line and see how or if it will run. Other than the carb itself, only a vacuum leak would cause the thing to not run at idle. Do you have a vacuum gauge you can put on the engine? Could you be a bit too far retarded in the timing? Just thinking outloud.

Dang,Fellers, you guys went into a time warp!
AK, could it be the power valve/ vacuum port to the power valve? iirc, the vacuum pulls the power valve closed, and as you open the throttle the vacuum drops and lets the power valve spring lets it come open to give more fuel- and if you run a lumpy cam, it can effect your vacuum- ( and did ford have different spec power valves for this?)- i think holly did.- dang, i could be wrong,these files are dusty- they havent been opened in years.

2100.....just thinking about this carb and your problems. Do you have the choke linkage set right and the cam back in for the idle settings in the right way? Is the choke now working or do you have to set it still. I don't think you mentioned this yet. Setting the idle cam could be all it is. If you have pictures of the set up? If the linkage closes too much, you could be cutting off the air, and making it die.
I would correct the float level to exact specs, reset the choke to center- check the spring to ensure it's mounted into the receiver/lever in the choke housing. If the linkage is off or not set correct, this might be your problem.

I do not miss carburetors. Not even a little bit.

That's because FI has been around for most of your YOUNGER life. LOL. You aren't that old, so I can understand you not being a carb person. It took me a while to adapt to FI and DIS. I had grown up with points and condensers. lol Now, it's second nature, but at first it was like pulling teeth to get me to adapt.
Bear.....glad to see you still popping in and sharing your thoughts. I hope that the job isn't being too rough on your new body parts. I know I really feel yesterdays work I did on lil Red. He got his new calipers, rotors, wheel bearings, and a few other things yesterday. I couldn't even move last night. Putting away my tools seemed to take an hour and it was only 3 trips to the shed. I can move okay today, but have to go out and bleed the system.

Choke is set to the middle. But I'll double check it. Here are some pics (should be 12)
Float level looks like about 3/16 to top of bowl

Is your truck a 75? The carb is a 2150. Looking at the set up you are showing, other than the side settings, which can't really be seen, you have things absolutely right. Check the side cam for the idle adjustment. Take all the vac. lines and cap them and the carb. See if it will run then. You realize, that this carb will run with the top off, so if you can set the float running and see what is going on from the top. Did you blow out the air screw holes? There are small ports that can get clogged if you don't air them out. Again, thinking out loud.
From what i'm seeing, besides the very clean install of everything, nothing seems out of place. Matter of fact, just about anyone would like to have a FE look that clean.
