OK, got it... nice write up! BTW, aren't the Edelbrock carbs prone to the fuel evaporating or boiling out when hot? Perhaps that is a factor.

It doesn't have these issues at any time the engine is running. It may evaporate from sitting for days, but no carb/heat issues (for me). I do run a thicker gasket, it may be about 1/3rd inch or so thick.
