Patrick,
Think yourself lucky. My dual quad QuickFuel custom carbs drain down into the engine within a few hours!
After spending most of last season stripping the carbs and replacing the gaskets I finally found the root cause - the main bodies are porous! Obviously poor quality castings from the far east...........
Now trying to sort the problem out with my engine builder but apparently Quickfuel were bought out by Holley a few years back and since then they have become unresponsive to supporting customer problems
