A KM320 is old enough that everything on it is mechanical, which makes it one of the more satisfying cooktops to service: there is no board, no code and no sensor, just gas, a valve and a spark. A burner that clicks without lighting almost always has a cracked electrode ceramic, and one that lights unevenly almost always has blocked ports. Both are visible on inspection.
