Weber 40 IDF is dripping Options

[malcolm2]

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.

One last thing. The lead (led, not leed) plug is used to plug holes made during the machining of the carb, much like the aluminum plugs which are swaged into the engine case during machining of the oil passages.

It's and imperfect World and sometimes things like this leak. That's why conscious and knowledgeable builders pull said plugs and replace them with threaded and sealed plugs.

Haven't seen a carb one leak, but I'm not the least bit surprised.
