Carb problem?

Awhile ago I posted about my carb backfiring...well I think I have it narrowed down now, but of course I still need help. I got the timing all set and vacuum leaks checked, but the carb still backfires at certain times. It's fine when just driving around lightly. It usually does it when I mash down on the throttle. So I think it could either be a bad accelerator pump or out of whack metering jets...does this sound right? I'm just starting to get a hold of how carbs work, I'm 20 and I've had all EFI until now. It's an Edelbrock 600 or 650 carb I believe.
Thanks,
Sam
