Carbs, Weber 44s Options

[cpavlenko]

I built my 1.7 to a 2.0 with 2 Weber 44s. When I get back from a good cruise and park it in garage, after bout 7 mins later I here a gurgling from the carbs. Fuel dripping on butterfly's. Stinks up my 3 car garage. Me and my mechanic are doing different things. The last thing I tried was pulling a nipple I put on the expansion tank where the charcoal canister line went to the expansion tank. Did another 50 mile cruise, and parked it in the garage and after 7 mins nothing, then a little drip. It was about 3/4 better taking the nipple off. Soooooooooo, what is going on, I'm confused and help would be thankful.

I see you are in AZ. Are you running it hot and then immediately parking it? That could be causing some fuel boiling? Have you tried a few minutes of idle cooling before you shut down to see if that affects it?

Do you have the fuel line entering the carb from above the level of the carb?

Sort of sounds like it could also be leaky float needle valves and the fuel is draining into the carb bowl via gravity. High fuel bowl level can then cause a bleed over into the carbs. Fuel line should enter into the carb body from below the carb. Make sure that as your fuel line crosses over from one carb to the other carb, that you aren't routing that crossover line higher than the carb.

I've seen people loop it up though the loop for the trunk torsion bars. This puts it higher than the carb and susceptible for gravity drain back if a float needle is worn.

I'm in Northern Arizona, and it's been in the low to med 70's.

also the carbs don't even have 250 miles on them. We checked the carbs and everything was good. Oh sorry for the double post. Also I'm running European headers.
