The current 'standard' needle is not steel but Delrin (that's plastic, ma'm). The steel ones are notable for leaking like sieves (hence the rubber tip) and the rubber-tipped ones go 'bleah' when they encounter any kind of stuff like ethanol, which despite efforts to the contrary, creep into the mix on occasion. The deal with Delrin is that you have to had a weight to the float. Lee at Skyport can send you the instructions; in fact, he can send you the weight, which gets soldered on. It's required. Like absolutely required. With a Delrin needle and a fresh seat, my carb hasn't leaked a drop in a year and near 100 hours of flying time. I can go away and leave the fuel on (but I don't) and come back and find everything dry and the header tank full.
