Hi Ivor. We have a 1928 8-90 with one of those Scheblers. I have lots of pictures of this carb when we took it apart. So, if you still need this info, let me know

Hello, I am seeking information to help a fellow Auburn owner. His car is a 1928 8-115 and the Carburetor is a Schebler Duplex with cast brass bowl number SX312. I am after any information on the correct air vale spring, needle valve seat (main jet) and correct needle valve number or taper. The existing needles have 10 rings or grooves and from the information I have are 7 degree taper, the needle valve seats are new from "Straight eight " and measure 0.039" the Air valve spring is 1.061" outside diameter 8 1/2 active coils, 3.9" long with 0.042 diameter wire. Any information appreciated.
Ivor.
