Hi, The 1932 Buick Reference book is a must, but I guess you don't have it? Also try locating "Marvel Carbureters, Design, Operation, Priciples of Heat Control" (I only have a bad copy of one page, sorry). I made 3 scans of the Referance Book p 25, 26 and 27, hope you find it useful. Your 1932 57S should have part no. 10-264 on the Carb. body and it's different from model 60, 80 and 90.
