Carburetor Specifications

356 Carburetor Rescue offers remanufacture of all the following:

Early Porsche 356 engines used Solex carburetors.

32 PBJ, and more commonly, 32PBIC / PICB on Normal engines, and the 40PBIC / PICB on Super engines. These are all single-barrel carburetors.

The difference between a PBIC and PICB is the presence of a starter jet setup on those earlier PBIC carbs, deleted in 1955.

Solex 40PII, sandcast aluminum dual-barrel carburetors, both short and tall, were used on Carrera and Spyder 550 cars. Pot metal 40PII-4 could also be set up as the "tall" Carrera carbs.

The dual-barreled, single-shaft Solex 40PII-4 is used on Porsche 356 Super 90, SC, and early 912.

Early Super 90 carbs had a tall, narrow breather tube. There are variations in the breather tubes until the wider, shorter ones used for the SC. There is a tubeless late S90 / early SC top correct for those models. The early SC carb also has S90 injectors. The short fat brass breather tube we see on the later SC's is also the same configuration used on the 912.

The Solex was offered as a grey pot metal carb with white cad (silver) hardware. Later, the 912's (1967 model year) appeared with gold cad hardware.

Very early Solex had a pot metal top, and that was changed to a cast aluminum top.

Beginning with 912 production in late 1967 (the 1968 model year), Porsche began using the 40PII-4 Split Shaft carburetor with gold irridite plating and gold hardware. These were designed for the stock vacuum advance distributors. Many owners replaced the vacuum advance with a stock .022 — when this was done, the vacuum tubes on the carbs had to be sealed off. Both styles are in use.

We offer a solid shaft conversion for the split shaft carburetor.

As a note, we don't recommend velocity stacks, but they sure look good! Especially on a set of 44mm Solexes!
