Description
Overview:
The Strangler Flap Spring is a genuine Zenith part designed for the Zenith 13TC carburettor used on classic JAP engines.

Suitable for use on systems built around the Zenith 13TC and frequently found on JAP 2A applications. OEM reference: 013650. Genuine status: Genuine Zenith part.
