If I remember correctly, and it has been a while, when the plunger goes down, the enrichenning circuit is closed, when it is up(cold or no voltage) the circuit is open.
Simple way to check is hook the 2 leads across a battery, and watch the needle...might want to measure it, before adding voltage, and about 2 minutes after adding voltage. I think you'll find it extends to close off the port inside the carb.
