running like crap

I recently bought a 1970 f250 w/ a 302. It ran great when I first bought it 3 weeks ago, but now it runs like crap. At full throtle it runs fine but when I lightly depress the pedal the truck lurches and sometimes backfires and shoots flames out the tailpipe. I can almost hear it just spitting fuel instead of a constant spray. Is it time for a new carb, or a simple fix?

Probably be best to start with the basics first. Vacuum lines, state-of-tune (plugs, wires, cap, points if it has them) if it has an EGR valve.. You know, start with the easiest and cheapest first.

what kind of a carb does it have? If it's the two barrel that thing is ridiculously easy to rebuild. I think the kit is about 10 bucks or so
