This carb came off of a running, driving car, but has been sitting on a shelf for a (big) number of years, so, the buyer would want to go through it with a kit before installing it. Everything works smoothly. The metering blocks are 5671 and 5673, and the 3-digit date code on the airhorn, 892, is the same as the date on the tag, 8JB. $900 plus shipping.
