This high-quality needle and seat is a critical replacement for Weber DCOE side-draft carburettors, controlling fuel entry into the float bowl with precision. If your carburettor is experiencing fuel overflow or starvation, a worn or leaking needle and seat is often the culprit. This replacement unit is ethanol-compatible and delivers consistent fuel flow under varying load conditions, making it ideal for both classic road cars and high-performance applications.
