Unhappy

This is a new problem I've been having with my 600 Edelbrock. It floods only when I start the car when warm. Performance is good and have no bogs or lean conditions.
I've reset the floats to spec, checked for crap in the jets and the metering rods are clean. I have 5.5 psi of fuel pressure and a new fuel filter, checked for vacume leaks around the carb, spacer, and intake.

The car runs great except for this one issue.
I'm running out of ideas.

Should I try lowering the float?

I had a Holley model 4011 that seemed to do the same thing. I have purchased an Edelbrock for my new engine and am hoping for good results. It sounds like it could be due to "heat soak" -- the fuel boiling over while the engine is off. I tried heat disipators but had no luck. I hope others will come in with some ideas!

Just a hunch, but do your intake and gaskets have an open hole for the heat crossover? If so get intake gaskets that block it off. I'm running an Edelbrock Torker II (heat crossover blocked) with a 1" phenolic spacer and a 650 Holley with no problems.

Are you running a choke? That sounds a lot like an electric choke on a rich carb. Electric chokes tend to cool off faster than the manifold heat type. Common problem. Don't get me wrong though. If the choke and carb are properly set it can eliminate hot / cold start problems. Keep in mind that if you touch the accellerator pedal after a brief cool-off period, you will set the choke. Maybe you should try not touching the gas when warm. Those old carberated cars had to be stroked just right. I had a 76 Chevy Pickup that you'd pump twice on a cold morning and barely have to touch the gas when warm. I think that is why people first started talking to their cars.
