Could it be a carb Problem?

Hey guys got a little problem. I got my car outta storage (my back yard) and it hasnt been driven in probably 2 years. Ive been tinkering with it here n there. Finally got in and headed out to my inspection guy. As i started out it was really hesitant, almost like it wasnt getting fuel. I pulled over and checked the fuel filter and it was full. I had a spare in the trunk so I swapped it out. There was NO change. I figured maybe it just needs run a bit. It did good if you pumped the throttle slightly. Every light i had to keep my foot on the gas so it wouldnt shut off. I then pulled over once more and adjusted my idle screws ..that helped a bit but it still had a flutter off idle. I then thought maybe my plugs being gapped a .045 (MSD ignition). I then regapped them at .035 and still the dame deal. This time i felt the headers and cyl. 1,7,4,6 were way cooler than cyl. 3,5,2,8. On those i couldnt even touch em. All the plugs looked about the same. My timing heat was right on the arch, the mixture was a bit black, and the bar itself was a bit gray/white. Could it be my carburetor?
