Weber 40 IDF is dripping Options

Nice day for a drive yesterday.... Drove some, filled up with gas and drove a bit more.



Woke up this morning to smell gas in the garage and noticed a pool of fuel on the floor.

I removed the air filter and see a drip in one barrel. 1 barrel is very wet and even has a pool sitting on one side of the plate. The others are wet, so they could be dripping, but less frequent. You know gas, it will evaporate pretty quick.

looks to be coming from the center of #14, Aux Venturi. I removed the Main Jet on that barrel (47 - 50), hoping to get it to stop dripping. I think it stopped.

What is causing this? (IMG:style_emoticons/default/WTF.gif)

I should add that Dual Carbs are new, set up at AC.net... now out of business. Last summer I fully adjusted, and sync'd them. Had been running really well, parked for about a month. Total of about 800 miles on the whole rebuild.

have not checked, but I did take the fill cap off for now. I just filled the tank. It actually spilled out at the pump. So it is extra full.

This tank has two small pipes on the top corners. Those pipes run up into the D-pillars of the bus and back down into the engine bay. On the upward direction of each there is an oversized bulb section.

These pipes are supposed to go to the charcoal filter, which i am not using. I have connected the pipes together with a hose in the engine bay.
