Set OfC Gaskets For 40 PBIC And 40 PICB.

The OE Match Carburettor Gasket Set is a replacement sealing kit for Solex 40 PBIC and 40 PICB carburettors fitted to early Porsche 356 applications.
x2 Required Per Car.

Fits:
  • Porsche 356 Pre-A / 356 A Super engines

Carburettor gaskets create seals between the various sections and mating surfaces of the carburettor assembly. These seals are essential for preventing unwanted air leaks, fuel seepage and loss of vacuum that can interfere with correct fuel metering and engine operation.

Over time, original gasket material can harden, shrink, crack or become damaged during disassembly. Reusing old gaskets after a carburettor has been opened can also lead to unreliable sealing. Installing fresh gaskets during servicing or rebuilding helps restore correct sealing and dependable carburettor operation.

What This Product Does:

  • Seals mating surfaces within the Solex carburettor assembly.
  • Helps prevent fuel leaks from carburettor joints.
  • Helps prevent unwanted air or vacuum leaks.
  • Supports accurate air/fuel metering.
  • Helps maintain stable idle and predictable throttle response.
  • Provides fresh sealing components during carburettor rebuilding.
  • Replaces hardened, compressed or damaged original gaskets.
  • Helps restore reliable operation after carburettor disassembly.
  • Supports correct sealing of the 40 PBIC and 40 PICB carburettors.

A carburettor relies on controlled airflow and precisely metered fuel. Air entering through an unintended gasket leak can disturb the mixture, while fuel leakage creates both running problems and a potential safety concern.

Symptoms Of Wear Or Failure:
Possible signs of deteriorated carburettor gaskets include:

  • Fuel seepage around carburettor joints.
  • Strong petrol smell in the engine compartment.
  • Dampness or staining around gasket surfaces.
  • Rough or unstable idle.
  • Engine idle speed that is difficult to adjust.
  • Lean running caused by unwanted air entering the carburettor.
  • Hesitation during acceleration.
  • Poor throttle response.
  • Uneven engine running.
  • Difficult starting.
  • Carburettor mixture settings that will not remain consistent.
  • Increased fuel consumption.
  • Visible cracking, shrinking or hardening of gasket material.
  • Gaskets tearing when the carburettor is dismantled.
  • Vacuum leaks detected around carburettor mating surfaces.

These symptoms can also be caused by worn throttle shafts, blocked jets, incorrect float levels or other carburettor faults, so the complete carburettor should be inspected during diagnosis.

Why Replacement Matters:
Carburettor gaskets are designed to seal accurately between components. Once the gasket material has been compressed and exposed to fuel, heat and repeated temperature cycles, it may no longer reseal effectively after removal.

A damaged gasket can allow either fuel or air to pass where it should not.

Replacing worn gaskets helps restore:

  • Correct carburettor sealing.
  • Stable idle.
  • Accurate fuel metering.
  • Consistent throttle response.
  • Reduced risk of fuel leakage.
  • Reliable starting.
  • Better carburettor adjustment.
  • Cleaner and safer engine-bay operation.
