on way home from work, my car ran out of fuel

Once i tried to give it more beans, the car spluttered, stuttered and what seemed like misfiring, with the exhaust popping loudly once in that time. but continued to idle fine.
once parked up on my street, whilst idling i blipped the throttle a couple of times and it continued to splutter, misfire and so on. but still continued to idle as per normal.
left the car for a couple of hours and tried again started fine but continued to splutter when on throttle
i identified the carb a while ago as a SU HIF type, when adjusting mixture and what not last summer.
up until this point the car has been running fine
any help etc would be a massive help
cheers
