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.

Do you have any insulators between the heads and the manifolds? Back in the day, when I used carbs on a 4-cyl, we used to use a thick insulator between the head and the short intakes. This hard plastic block was supposed to (and seemed to) keep the carbs from heat soaking and boiling the gas remaining in the float bowls.

Not sure if they still have those insulators or not. I haven't used carbs in years, but I still have a set of them in a box somewhere. I converted that engine back to stock FI before I converted to a 3.2 six.
