Zenith made a variety of venturi sizes for the B carburetor. This was probably because many were used on stationary industrial engines. Some years ago there was a fellow selling off new Zenith A and B parts on eBay. He had one each of sizes 17, 19, 20, 22, 23, 24, and 26 for the B-type carb. There was a flurry of bids on the larger sizes and I mistakenly bid on the 17. I still have it and had a notion to install it just for the inspection if my area ever imposed annual emissions tests on vehicles.
