I will try that and see if it helps.

My setup is not too different - a LR 427 intake with two 1850 carbs on it. The exhaust is enough to get a cold shoulder from the wife but if I look down the primary throat on the rear carb about 10 minutes after shutting it down I will see fuel starting to drip from the accelerator pump shooter. That fuel on hot engine parts sets up a real stink that lasts for hours in the garage. I have heat shields under mine which helped somewhat but not a complete fix. I do have my floats set to hold fuel just below the sight ports and Patrick probably has a good point about taking them down a bit more. But I think the main issue is the accelerator pump sitting right above the intake and heat off the intake expanding and forcing fuel out the shooters. I've also cut a piece of aluminum faced insulation and put under the accelerator pumps but it hasn't been a complete fix either.
