Todays fuels contain many elements to promote less harmful pollution including bio-ethanol and many other potentially harmful additives (to the fuel system, not the environment!) which play havoc with the carburettor internals.
Failure to drain the carburettor/s for the winter lay up allows the petrol to turn into varnish, clogging up the carburettor jets and coating the float and float Chamber, sometimes to the point where it becomes so difficult to clear, replacement of all the various internals, or even the complete carburettor assembly may give preferable results?
Other suggestions of carburettor parts, both internal and external you may require are listed below:
