The new style nt has a barrrwl nut that connects the gas line to the carb the two red washers that contain the gas have failed does anyone have thus problem or ideas on how to solve it. I have tried gasket sealer making washer from paper gasket bike innertube rubber but it still drips. I think I am going to get the old style carb, I only need one shut off valve but I'm wondering if I'm going to loose power since I have a 66 skyhawk and I heard the old ones are for 48 s. I do live at a high elevation so Maby a bit smaller wouldn't hurt. Thanx all keep riding
