Carb Heat Soak

Installed the heat insulator gasket. It has helped slightly with the hard start after hot but the issue is still there. It did however help with overall engine temp and running about 10 degrees cooler than usual so there was some benefit. I did remove the unnecessary fuel regulator since I am running a Holley Red Electric, which doesn't require it to rule that out as a possibility but did nothing to improve. I also checked the spark plugs and they look good. Any other suggestions here to trouble shoot would be appreciated.
