My trusty old mower is no longer trusty. It starts OK, and runs for a
couple of circuits of the lawn, then stops dead. The stop is so sudden it
almost seems electrical,
Does it have a "stop" wire somewhere on the throttle linkage? I have known
these short out and cause the sort of problem you describe. The work by
shorting the ignition to earth when the throttle is closed.
