Renewing as many of the wear prone working parts when carrying out a carburettor refurbishment is a sensible course of action.
Problems can occur on old carbs and serve to reduce the performance and reliability, but, can be addressed by a complete strip down of the carburettor, sonic cleaning and then replacement of any part that carries signs of significant or even partial wear.
