79 deville popping thru the carb

hi all, i'm having a problem working out the bug in my 79 deville. i bought it from a guy who had it in his garage for years, it didn't run when i bought it as it had been started for years. i've got it running now but it is popping thru the carb when i accelerate somewhat hard, also the 4 barrels don't seem to be kicking in properly. i've put in a new fuel filter, new plugs,wires and ignition module,cap and rotor. i had a friend time it to 38 degrees i believe and set the choke spring. the choke closes when cold and opens wide open when warm. When i first got it running it smelled of old gas terrible but now smells right on. I'm thinking the carb needs rebuilding but i'm wondering if i should run it on the road to clear it up. any imput would be appreaciated. thanks
