Yep, replace the needle and diagphram. - when it splits it goes ultra rich, although usually this results in a no-start condition...
Check the ignition timing and make sure the choke isn't sticking on, could also be a sticking needle valve causing the carb to flood.
Is the tickover lumpy?. Should be a plug under the float chamber, remove this and use an 8mm socket and adjust clockwise to weaken the mixture, try asking a garage if they'll check the CO content and adjust the mixture for you. Should be about 1.5%-2% CO at 800rpm
