Jim Yergin Posted April 6, 2015 Share Posted April 6, 2015 Here is a picture of the intake manifold off my recently acquired 1956 Thunderbird. There is a plain sheet metal screw in the middle branch plugging a hole. Can someone tell me what is supposed to be attached there?Thanks.Jim Yergin Link to comment Share on other sites More sharing options...
paul2748 Posted April 6, 2015 Share Posted April 6, 2015 (edited) The hole where the screw is is for the heat tube for the automatic choke. You should find another hole at the other side of the intake. There is a tube that goes through the intake. They rot out. Replacements are available. There are fittings that go into each end of the tube The right side ones goes into a short tube that goes into the automatic choke. On the other side, there is a piece if tubing that goes into a hole in the carb under the air horn.
