Question on that hot soak issue. Does it get better in cooler weather? It's been in the mid 90's with about 45% humidity when it does this.
Yes, it's almost always a mid-summer situation, with enough running time to get up to normal operating temperature, followed by a stop of 30 minutes or so, just long enough for the gas in the float bowl to heat up, expand and dribble down into the intake. If you stop for a couple of hours, the gas has a chance to evaporate and the condition doesn't happen, or at least it only takes a few seconds of cranking to clear the rich mixture. Unless there's a leaky injector on a modern engine, hot soak doesn't happen because the injectors need a pulsed signal from the computer to open up and allow fuel to flow.
