backfiring through intake

this question is for my 73 240Z. When I try to cold start it, it cranks for a while and then it eventually starts but I have to gas it, and sometimes when I gas it, the idle drops to a point where the engine doesn't want to start anymore. other symptoms include backfiring through the intake and sputtering while I accelerate. the car gets spark but i'm not sure if it's getting the proper amount, and i'm not sure if the fuel lines are clogged. what's the best way to check all your fuel lines? and also for vaccum leaks?
