Same here. Until this latest carb (Holley 390) I've not used a choke on my dailies in decades. A few seconds of "acc pump patting" the gas at cold-start, and drive off. A water choke and hot-air choke are way too slow in this mild climate. The electrics have worked best. Had to convert hot air on a YF to electric on my wife's daily. Use 100% voltage, and the choke is fully unloaded in about one minute. Anything longer = stumbling rich.
It seems that a water choke would be incredibly slow and wasteful of fuel. 0% chance of considering it down here in the south.
Living where you do, anything more than 1-2 minutes of choke is flooding the engine. How long does the water take to heat up? Maybe in the artic- Alabama, no way is water choke going to be quick enough. (Strictly an opinion, based on warm climate experience.)
