Hard Starting After Warmed Up.....Arrrg

How long of a delay until it starts to fire? I'm running an AFB and when it gets hot it takes anywhere from 2-5 seconds. Even if the fuel isn't technically "boiling" the heat will cause gas vapors to seep out the boosters and fill up the intake making the mixture super rich; when you go to start the car the engine has to crank over a few times to clear out the over-rich mixture and get enough air in to make it "burnable" again.

I've found holding the throttle open a tad when cranking it helps get the air in faster. Don't feather the throttle that's just squirting more fuel in via the acc. pump and making the problem worse.

Modern gas vaporizes much faster than older pre-ethanol 100% gasoline.
