Drop the float bowl and check the gasket doesn't have a twist in it. And check the float l evel at the same time. - Regards Keith J160 --- On Tue, 28/4/09, Rosalie wrote: From: Rosalie Subject: JabiruEngine-List: Carby leak Received: Tuesday, 28 April, 2009, 6:45 PM I noticed a leak from my carby last night after a 1-hour sunset flight. Th e gas dripped from the bottom of the float chamber. Today it was dry. I inspected all lines and connections with the fuel pump on. Nothing leaked except the float chamber. It is not a flowing leak. Just wet enough to ca use a drip every two minutes. Kinda like condensation on the side of a cold beer can on a hot day. The drip stops after about 10 minutes. So, after the drip stopped I dried the side of the chamber and started the motor without the f uel pump on. Same result. A leak and drip on the side of the float chamber. Any ideas on how to stop the leak, or what is causing the problem? I would like to take it to Jabiru's distributor for a look, but I am hesitant to fly with a gas leak of any kind. Even a slow leak. Thanks for any help.

After you have the bowl off, go one step further and remove the float and needle and see if there's any VERY small object on the needle or the seat that could be causing the drip, then reinstall.

The fuel pressure is over whelming the float needle. Bing has several float needles with different springs at the end next to the carb float. Originally mine had an orange tipped needle with the weak spring. I changed to a black tipped float needle and the overflow was cured. My friend tried changing to the black tipped float needle but only had some success. There are two Bing floats a white one and a black one. The original is white, the black exerts more force and when he installed the black float, his bowl overflow stopped. You can get both items from Bing. My engine ser# is 988. 40mm Bing. Chuck D.
