you could buy a new carb only to find the problem's still there, it's your choice, for the sake of twiddling a couple of screws and checking that clean fuel is filling the floatbowl, the float is working correctly and is at the correct height, also worth checking the valve clearances, guaranteed it's something simple!

could be an air leak on inlet but sounds like the mixture is way out, try turning mixture screw inwards all the way then back out about one and a half turns, turning it either way for fastest tickover then turnig idle screw anti-clockwise to bring revs down to correct tickover speed.
