A fuel valve would add weight and another component

hold less than half a pint of fuel, but many owners empty
the fuel tank before running the carb dry for storage.

Also, the fuel line is entirely internal to the shrouding. Almost
impossible to put a fuel valve in an accessable location. Dumping the
tank before beginning is no problem and the dumped fuel can be used in
lawn mower or other equipment.
