Or stop switch. When I had the Chief I once had a bad mag ground that
prevented the mags from shutting off. Since the Chief has no idle cut
off mixture all I could do was to shut the fuel valve off and sit and
wait, and wait, and wait.

With the old Stromberg carbs on those things one can maybe
run the RPM up to 1200 or so, yank it back to idle, and just as the
engine is reaching its lowest RPM you slam the throttle wide open.
It'll usually quit. The lean mixture on decreasing RPM and the lack of
an accelerator pump will starve it enough to quit.
But it's still better to run it out of fuel, for safety. I do
that with my A-65.
