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.  |

I do trust ACN as most of my carb knowledge came from John over several emails when I was just starting out learning them. 12mm is fine and if anything would shut the flow sooner, so not as filled.
Was the regulator always used with your setup? |
