Quadrajet Carb Leaking?
I bought a remanufactured Q-Jet for my motorhome when I put the "new" engine in. Let me first say that it runs awesome. Plenty of power, no stumbling, smooth idle. When it's warm anyway. The choke ope...

turbojimmy,
I'm certainly no expert on these things but, I have had a few Q-Jets apart in my time. I personally think they're one of the best carbs ever designed. Many have had issues with them but, if properly put together and adjusted, they're designed to work in a maximum range of fuel/air/throttle positions. With that being said, of course as you'd know, the two main reasons for ANY fuel OUTSIDE it's normal working area INSIDE THE BOWL, is due to a bad or broken gasket or, an improperly adjusted float or, a malfunctioning float and or, a possible micro-piece of dirt or debris in the needle/seat area.
Taking those Q-Jets apart is a tiny feat. Your arrow is pointing right at the main metering rods. They typically lift as the throttle is opened and, if you've never seen them, they're "stepped". The more throttle is use, the smaller the steps are as the higher they're lifted by the movement of the main and secondary throttle plates.
But as for your particular area for your fuel, I'm wondering, is it possible that your accumulating "oil" from possible blow-by? Again, it's only been a zillion years since I messed with those. Good luck.
