I have a 1984 Jeep Cj-7 and my Carburetor needs to be fixed, should I sell it?

So here is the situation, I'm 17, I inherited a 1984 Jeep Cj-7 from my grandpa. It was a gift so it would hurt him if I were to sell it, however I have already had to replace the fuel pump, master cylinder, and do some major electrical work (which there is still more of to do). Now my carb isn't functioning properly and it's time to rebuild it (its also a webber carb, which was added on five or six years ago, so it would be difficult to change all of the modifications put in place to install that original stock carb that was there in the first place). I also need to drop my fuel tank and clean it, because the car sat around for five years with fuel in the tank. I have heard that CJ's are worth money and can be quite collectible, and gain in value as they get older. My dad is also a mechanic but it is still expensive for him to spend time fixing my car when he could be working. I am also going to college in 4 months in San Francisco, and if the jeep were working I would still have to leave it at home, because it costs to much money to park it in the city. So basically my question is: Should I hold on to the jeep and fix it, or is it a good time to sell it and get a car that doesn't have so many issues, and how much does it cost to rebuild a carburetor?
