On a hot start, I cool the pump body by running the battery operated
pump with the mixture closed in the Idle Cut Off position. This (on the
lycoming IO-360's Ive used it on) runs fresh "cool" fuel from the tanks,
through the pump body and back to the tank. I do this for a full minute,
then prime and start as a normal start.

Other options are to intentionally flood the engine (mildly so) and then
do a flooded start procedure (throttle wide open, mixture off and you
seem like you need 3 hands..)

Thanks for the explanation EDR. My question then is: If the engine is
shut down by pulling the mixture control to idle/cutoff, where does
the engine get the fuel it needs to start again when you attempt a hot
start 15 minutes later? You aren't supposed to use the auxiliary fuel
pump and the mixture is supposed to remain at idle/cutoff during the
start in this situation.

Throttle is supposed to be advanced 1/4", but since the mixture
control is closed and the engine had stopped for lack of fuel, where
is the gas coming from to start the engine?
