440 melt down

It may be worth checking your float levels too. For what it's worth, my Edelbrocks/AFBs hot start a little hard on hot days with a hot engine too. With oxygenated gas, I've gotten used to cranking it for a second, then slowly pushing the throttle to the floor and cranking it until it catches. It's usually a couple of seconds. Unfortunately, it's the nature of the beast these days. A nice insulator will help. Obviously, make sure your timing is on target too. These engines seem to like a lot of initial timing these days, and that means reducing your total timing to avoid detonation, etc. Good luck!
