Engine pops (fuel related?)

Engine pops (fuel related?)
Hello, I have a questioned for the seasoned professionals
I own a 1971 Jimmy with a 350 engine and some aftermarket edlebock carb
The engine idles fine but here is my problem
From a stop if I push the gas too much the engine kind of stalls for a bit then catches up with itself and runs fine
also let’s say I'm doing 40 mph and I push the gas a little more to gain some speed- the engine will start to pop lake crazy kind of like it backfires but if I stomp it to the floor the engine goes and performs like normal... Any ideas as to what could be causing this?
Thanks

RE: Engine pops (fuel related?)
It sounds like the carb is probably running lean. Try opening the air fuel mixture screws 1/2 a turn each and see if that makes a difference.
