My car won't idle correctly and dies if I let go off the gas pedal.
So as titled stated... my car won't stay idle... it idles at 500 and it will slowly dies. I give it a little gas then it'd stay up a bit and repeat the same.
What happened was...
I had a fuel leak from the fuel hose going to the carb... so I replaced that and it's working fine. I was running low on gas... and my driveway is not a straight road so the gas was probably not feeding in to stay idle so it died on my driveway... I poured in gas... tried to start it and it wouldn't start even I let the fuel pump on for a bit. So I tried to start it again and again... and one of the starter cable was burnt... there were smoke coming out so I finally gave up. Next day, I got that fixed, started the car up and it started fine but the car sounded a little rich... it ran well though so I went to the gas station to fill in some gas. The car wouldn't start back up after I got it filled up... it was odd... so I left it there until the next morning and fix it with my bro... first thing we checked was to see if the spark plugs were wet and they were, kinda burnt too... but we flushed the float boat and got the plugs dry and clean so we can get the car home... it started up... at first the car didn't sound like it's going to die... so I thought it's fine until I reach up to an intersection... my car started to idle at 500 rpm and the car was jerking when it's not even moving, so I got it home and it died on me right at the moment when I was fully stopped. Took out the plugs and its burnt again... so I just ordered new plugs... had to wait 3-4 days so I got Autolite instead today. The car started up but I had to jump it... then after the choke .... the car started to want to die again at 500 RPM... I don't know why this is happening... it was running fine until the car died cause it ran out of gas.
Me, my bro, and my friend thought about maybe it's the cap and rotor? But they are like new condition... spark plugs wire are fine, my battery is about 6 months old... we can't think of anything else...
Can you guys please tell me why this is happening??? Thanks!

Ok... I found the idle speed screw last night and played with it to the correct RPM. It worked! I thought the car is going to be all good, so I took it out for a spin... it ran pretty smooth for a mile or so then when I was coming to a stop... the car started to idle very low again... I tried very hard to give it gas to pump the engine back up... it didn't work and it died. We had to push the car back home... now I have no idea what can happen? I checked the float boat and it seems to be filled again! I don't know why... is it time to check the needle and seat now or... what should I do before that? Something might be more simple?

What fuel pressure are you running?
Have you changed the fuel filter, as asked priviously?
Have you tested for vacuum leaks?
Your valve is gone from the manifold, which is good, but how thick is that cover? Is it sealed with Hylomar, or something similar, or not? The plate looks thin to me.
I think there's a combination of problems here. First one is that your idle speed was too low, which you've fixed.
You REALLY need to get a Haynes manual for your car. It will tell you all the troubleshooting basics.
