Difficult starting when hot....
After reading all the threads about "difficult hot starts", I began to wonder....if the fuel boils out of the bowl when it's hot, shouldn't the "no fuel in the bowl" situation be the same after the engine cools down? If the engine is hard to start when it's hot because of lack of fuel, then how can the engine be easier to start when it's cooled down...??

2 different problems ?
1 fuel perculation- fuel boils off in the fuel bowl.
check for this by veiwing down the carb, and pump the gas.
2. Heat soak of the starter is a different problem-- slow or no cranking.

The starter works perfectly...cranks strong and continuously.
As far as the fuel perculating, how does one prevent that?

I suspect that the generations that have learned to drive in the fuel injection era have never had a need to learn techniques used to start a hot carbureted engine - the engine control chip makes the needed adjustments for them. Outside of this and other classic car forums, the terms 'vapor lock' and 'flooded engine' (gasoline, not hurricane) have pretty much dissappeared from the car owners lexicon today.
Seems to be similar to the 'runs hot' threads too. Today's aluminium radiators and electric fans have pretty much removed 'boil over' from use too.

GM used to sell these over the counter (not sure if they still do) and were part of Calif emissions systems years back.
