You are buying ONE ONLY (not all) new old stock vintage McCulloch BDC-14 carburetor body. Body is new and parts were removed and sold separately back in the day. These bodies do not have a venturi. It had to have been removed by McCulloch. Not sure why but there is a "B" stamped after the BDC14 Check pictures for condition. email questions.  I combine shipping. Check out my auctions for new international and american go kart and quarter midget barstool racer, powered drift trike, enduro racing parts and as always vintage go kart racing parts.
