There's one other point about hard starting that gets overlooked, re" a 
hot engine.

Corvair carbs get hot when you shut off the engine after a long uphill 
pull, like running up the uphill grade on I-81 from outside Roanoke to 
Christiansburg, aka "Christiansburg mountain".  It's not the steepest 
grade in the world but it's a long stretch and it's steep enough to make 
you wanna downshift unless you have some genuine horsepower.

I do not recommend doing it at 70 in a '63 Spyder because the engine 
will try to stay in boost the whole run, NOT a good thing.

Got off the grade at C-burg and into the gas station to refuel.  Tried 
to restart, engine labored with that rump-rump cranking like the timing 
was too far advanced, hot engine and heat soaked carbs that refused to 
meter correctly even after you kinda cleared the massive over-rich 
condition from carb boilover.  This, a '65 Corsa w/140.  I played a 
hunch, poured a couple buckets of water over the carbs and heads or at 
least as much of the heads as I could reach from under the decklid, 
mostly just onto the carbs. Much steam. The car then started right up.

I did the same trick in the driveway with the '62 ragtop (w/'66 110) 
that had been idling too slow and got hot, wouldn't restart, took a hose 
to the carbs and then it started right up.

Modern gasoline just too volatile, boiling out the carbs?

Me too, it's how I learn stuff.
