I'm not patient enough to wait for someone who knows what they are talking about (referring to myself as the one who doesn't know he is talking about), but isn't the float needle and seat at the top of the bowl? And if that is so, how can fuel "drain or be siphoned" back down stream to the fuel pump due to a leaky pump valve?

You are right. The fuel can't drain out of the bowl. It will evaporate though. The fuel in the line & a fuel filter in the line can drain back. Then the pump has to work several times to start filling the bowl. That is why a good accel pump is necessary to prime the carb for a quick start. All The fuel in the bowl will not evaporate overnight except very high temps. If it sets about a week or more it may be hard to start but again a good accel. pump will squirt fuel into the carb throat as soon as the bowl is partially filled by pumping the gas pedal. I feel the fuel pump & accel. pump need to be in good cond. for easy starts.
