Nev I had parts delivered from xair in Bangalore to my door in Gippsland in 5 days with ups. I was impressed. It takes that long to get items posted from Melbourne with auspost. 1 Link to comment Share on other sites More sharing options...

God I love Aircraft Spruce and UPS ☺️ Meanwhile something I ordered from Toowoomba the same day still isn't here.

With my tool I can with care do them myself). Check fully also the butterflies are in correct best to mark a reference with a marker pen. They don't fit both ways as have a camphor on there edge (Tripple check or don't peen screws until fully checked.) 2 Link to comment Share on other sites More sharing options...

But I found a great write up on CV carbs from this BMW guy. Quite informative: https://bmwmotorcycletech.info/bingcv.htm Since you've had them apart, a question about the slide where the diaphragm spring is. My feeling is it wouldn't be lubed- after all, the carby slide isn't lubed. Am I correct in that assumption?

Or put more simply, is ANY part in there lubed? I suspect not, but thought I'd ask 🙂 Link to comment Share on other sites More sharing options...

facthunter Posted October 5, 2023 Share Posted October 5, 2023 Very risky to reuse any "O" rings. They harden and go out of shape. The butterfly as well as being in the right way has to be centred before any of the screws are tightened. The chamfer or angling of the sides has to be taken into account in locating it. Why remove it anyhow? IF you are not familiar with these things don't learn on one that's in a plane. Nev 2 2 Link to comment Share on other sites More sharing options...
danny_galaga Posted October 6, 2023 Author Share Posted October 6, 2023 I'm replacing any easy to get ones since I have the kit. The current O rings are in great condition, still soft but I got the basic kit for the choke gaskets, and the bowl seals. Might as well use the others. 1 Link to comment Share on other sites More sharing options...
danny_galaga Posted October 17, 2023 Author Share Posted October 17, 2023 (edited) Mystery solved - I had the fuel IN line and fuel RETURN line mixed 😄 It meant that there was only a trickle of fuel. The hose to the left carby is much shorter than the right so what little fuel there was mostly went to the left, making it seem to run like one carby was faulty. I ran it for about 20 minutes once it started to see how hot it would get. About 85° which is nice. Finally got to do radio check with the engine running too. Yay! So in the end I needn't have even taken the carbies off at all! But at least I now know a bit more about the insides of Bing carbies.
