How Long Does it Take the Gas to Evaporate Out of Your Holley Carb?

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

Yikes. I've never heard of porous main bodies. I do know that the dichromate has slowly dripped off my Holley, and "dripped" really isn't the right word, it seems more like a very, very fine powdery mist that just drops off from the bottom up. It actually leaves a stain on the manifold that looks like an oil stain, but that comes right off with a paper towel and soap. But my Holley is now over ten years old, so I guess it's too much to ask for the coating to stay on that long.

Check the power valve Patrick...
