Mike - the downdraft fake Carter W-0 carbs for the Willys Jeep are of such poor quality, that, if one removes the fake from the engine after 500 miles (assuming it lasts 500 miles

) and tries to set the fake on one's workbench, it will roll off. The zinc alloy (pot metal) is so poor that the flange will have warped maybe 50 thousandths. It is no longer flat. And people gripe about idle quality if the throttle shaft wears 3 thousandths.
But depending on the greed of the seller, it only costs from $89.95 to $139.95.

Jon.
