This is a brand new Austin Healey 3000, MGB, Triumph Spitfire Foat New 378-470. Comes with gasket and float. Please message me with any questions.

“With the non-adjustable floats, to lower the float level you add thin metal shim washers under the needle's seat to achieve the proper spec. To raise the float level, add gaskets between the float bowls and their lids. Because of the geometry, a thin shim or gasket can make a significant difference, so you'll have to experiment. Shims and gaskets are available from Joe Curto”
