Topic: Stromberg 97 ID


usered    -- 03-19-2023 @ 5:14 AM
  I purchased a box (10) of old used Stromberg 97 Carburetors. I have a book that ID's 97's as:

On the bowl 1-1 with a circle around P-21957 31/32, with 97 on the opposite side of the bowl

Mine have the following: See pictures

Several have the above except have the number as 21951
A couple have B2 instead of 1 -1
Some have a large 97 and some have a small 97
1 just has the 31/32

Can someone tell me or point me to some specifications that might explain these codes?

  The P- numbers are Stromberg casting numbers the tops and the mid section have different numbers. The model 40 is typically cast as P-19402 top air horn and P-19401 bowl.
The 48 is P-20692 air horn and P-20671 bowl.
The 97, P-21942 air horn and P-21951 bowl.
Remember the model 40 and 48 are 1-1/32 venturi and the 97 is 31/32. The Stromberg "made in Elmira, NY" is slightly different.
Ford would rebuild their own production carburetors so to distinguish, Stromberg cast a small 97 and also added Fords part number prefix to the casting such as 67 to the air horn and bowl body for the 1936 Stromberg 97.
