This pair of recently rebuilt Weber 46 IDA triple-downdraft carburetors was disassembled, cleaned, vapor blasted, and reassembled with new seals, springs, jets, and tubes, with zinc coating applied where appropriate. They were only used for dynamometer testing on a 2.7L flat-six engine and come with custom billet top plates, bubble air screen filters, and rain hats. These 46mm carburetors feature built-in emulsion tubes, 42mm chokes, 135 main jets, 145 air correction jets, and 55 idle.
