I would suspect that with the carb, having the throttle closed would reduce the amount of air coming in quite a bit, and so you wouldn't be using the same amount of fuel per rpm as you would if you were powering it to that rpm. The throttle plate is after the venturi, right?
Also, I wonder if you have an electric fuel pump, or the more likely manual fuel pump. If you were lucky enough to have the electric fuel pump, a on off switch for the pump would be nice; you'd only lose the gas in the carb's bowl, and refilling it wouldn't take but a second. But I suspect you'd have a manual fuel pump, which makes it a bit trickier...
