Use the insulater gasket. This is a common problem with the Eddy carbs.
I have a '68 Super Bee running the Eddy carb till I can give the OEM Carter a replate & rebuild. I kept having a problem with the car starting after warm up,acted like vapor lock. I used a 1/2 wood spacer,problem fixed.
I'll put that on today to see if it helps. Our problem is a little different because my car starts back up no problem. My issue was punching shorty after hot start. Under normal driving conditions after hot start, no problem.
