Carter YF Carburator Problems...ahhh!

Here's my story: I am currently in the midst of restoring my great grandfather's 1963 CJ-5. I have gone as far as to removing the body off the frame. Cutting to the chase, I rebuilt the carburetor in the spring, and afterwords the engine ran like brand new. I removed the lines and replaced them, and never tried to start it again until this fall, finding out it would not stay running correct.
It would barely idle, and as soon as you gave it fuel it wanted to die, but then as soon as the throttle went back to idle it idled up for a minute then back down to about stalling.

Not to sound cocky, but I am pretty mechanically inclined and assumed the carburetor just needed a little cleaning. after pulling it apart, I found that it didnt even look as if i had rebuilt it that spring. everything was all cruddy and dried out. I cleaned it anyway and put it back on, still not running right.

I bought a new rebuild kit, and replaced all the parts, again, tonight.
Putting it back on the jeep i figured it would run fine. NOTTT! from what I can tell the plunger pump pumps up when you first give it throttle, but after you give it that first pump with the throttle the plunger doesnt set back down, but stays int the raised position, making it only pump once. On top of that, it doesnt seem to be putting any fuel out at idle....

I do not fully understand the whole thing. I understand the plunger pumps fuel in when you give it fuel, but i dont know who the plunger re-sets back into the lowerd position, or how it squirts fuel out for idle.

can someone please assist me and explain to me.

I cant figure this out. I am missing something.

P.S. I have checked timing and dwell.
