72 125hp Sensor shorted?

[72evinrude]

When I retard beyond 5 deg. to get lower rpm the engine will run for a while and shut off like ignition turned off.

Also when checking the sensor gap I forgot the key was on and I recieved a shock. Should this happen? At low idle maybe a voltage leak is shorting it out?

Thanks in advance,

A couple of things come to mind. You could have some debris in the the carb idle circuit passages such that it just won't run ok at low idle speeds. Also possible that at low rpm's that the stator is unable to generate the voltage necessary to fire the ignition to keep it running.
