I was talking with another member about an issue I have when it's hot out and he told me he has the exact same problem, and the same carb.
This is it.
Edelbrock 1506 600cfm runs and starts well all the time exept when it's hot out.
His car does not have the thermal gasket between the carb and manifold (But he has a hood scoop)
My car does not have a scoop but has the eddie thermal gasket.
So it seems to be a wash
(His gets more heat to the carb but has better ventilation and mine has no extra ventilation but has the thermal barrier)
This is what we found out about the problem from chking and searching websites like hotrodders.com as well as quite a few other sites.
Eddie carbs are more susceptible to heat for some reason than most other carbs, but more so with ethanol mixed fuels because ethanol boils at a lower temp than non ethanol gas. (Eddies are more prone to heating the fuel, and ethanol makes it worse)
If I pull into a store or whatever, and come back out in a half hour or so the car does not like to start normally and acts like it's a little flooded.
Once it does start it acts like it's flooding as if the float was stuck and I can smell raw fuel and have to keep my foot in it for about 60 seconds or so till it clears up and runs just fine again. (Revving it clears it up sooner)
What we decided was that the fuel inside the carb itself was trying to boil. (when new fuel was introduced to the carb bowls the problems cleared up) leading us to determin that the fuel that was actually inside the carb was the problem.
Next I started more research.
Why Edelbrock, why is fuel boiling when it's 90 degrees out?
That's when the answers started coming in.
One of the searches turned up a page in the Eddie manual that states "Methanol mixed fuels of 10% or more are not recommended in these carbs as the methanol will deteriorate the rubber parts and also corrode the metals. (I guess I missed that before this)
I guess I'll have to pay more attention to what the mixtures are at the satation.

A little beside the point of this post but good to know, so now where do we go from here?
Ok then, now what do we do about the heat issue?
There is a company called Coolcarb and the website is www.coolcarb.com that sells a product that claims to solve this issue.
If you watch the first video on the page it does explain how the product works and they seem to prove it with a thermal gun.
Does anyone have realtime experience with this product?
It's about 50 bucks so I would like some real info from real users before I order one.

Blended Fuels
Typically, two types of blended fuels are available: Gasohol and Gasahol. Gasohol is a blend of not more than 10% ethanol and gasoline. As long as there is no more than 10% ethanol
mixed with the gasoline your carburetor will function properly. As the percentage of ethanol climbs above10%, a richer A/F ratio will be required. Also, because gasohol is more volatile than
gasoline, hard hot starting and poor hot weather driveability may result.
Gasahol can be a blend of either ethanol, methanol or other alcohol with gasoline. Methanol blended fuel should not be used in your Edelbrock Performer Series carburetor as it will cause
corrosion of the fuel system components. It can also cause rapid failure of seals, gaskets, diaphragms and pump plungers.
Always check to see if you are using a blended fuel. Although the pump may not indicate the fuel is blended, it is always advisable to verify the type of fuel the station carries.mixed with the gasoline your carburetor will function properly. As the percentage of ethanol climbs above10%, a richer A/F ratio will be required. Also, because gasohol is more volatile than
