Somebody sells gaskets for the Marvel, but I've long ago lost the address. I think that's all that's available. Maybe somebody on this board has contact information. I haven't searched "Marvel Carburetors" to see if it's archived. They require a slightly different fitting on the gas line. Or at least mine does. I'm not using it any more because the float seemed to stick sometimes and I had about a dozen good Tillotsons, which I like.
