New Carb Time??

[70sChevys]

About a month ago, my truck started running rough when I started it up first thing in the morning...sounded like it wasn't getting gas, so I popped the hood and found the carb was leaking from the top and the front two bolts were loose. (It's a Q-jet)....this fixed it and I drove off. This morning it did the same thing and tightening the bolts didn't help....it wouldn't start. I'm going to try and prime it to start it and check the other bolts, but I'm wondering if there's anything else easy to replace that will solve the problem...if not I'm gonna get a 1406 Edelbrock for it.

So for you carb guys....what can I check to fix it (I could really use the $250 elsewhere!).
