Carburetor Question - Is this a good call?

We all need to remember it worked well before. No need to change a bunch of stuff if it worked good before.
back in 2004 when i was in college i used to drive it 80 miles one way to my folks house for a weekend home, no problem. Now is a very different story. The difference between then and now is I did a core exchange once with it, and the "new" carb has gone through 2 rebuilds.
