Our car is equipped with a STROMBERG carburetor model B, number 4. This appears on the side of the carb as “B NO. 4” Stromberg made A carbs, B carbs and C carbs at this time and generally speaking the designation dealt with the throat size.
Here is a bit of contemporary advertising for the Stromberg carburetors:
We understand that although our car has a Stromberg, other Michigans were equipped with SCHEBLER brand carburetors. Mike Howard’s car has a Schebler.
