Description
Overview:
The Jet Valve Needle Locking Nut is a small metal fastener used on Villiers petrol engines to secure the jet (mixture) needle after adjustment. Designed for classic Villiers units such as the MK10 and MK12, it helps keep fuel settings stable under vibration for consistent running and reliable starting. This is a Genuine Villiers OEM part, made to the original specification for a precise fit and correct function within the V Type carburettor assembly. Supplied as vintage, unused old stock, it is ideal for restoration work or routine maintenance where the original nut is missing, rounded, or damaged. Durable construction and accurate threads help ensure smooth operation and preserve the performance of older Villiers engines used in garden and construction machinery.
Key Features:
- Genuine Villiers OEM locking nut (1113X4E) for assured compatibility and fit
- Secures the jet needle to prevent movement and maintain correct mixture settings
- Metal construction for durability under heat, fuel exposure, and engine vibration
- Precision threads for smooth tightening and reliable clamping force
- Helps stabilise idle, throttle response, and overall carburettor performance
- Suitable replacement where the original nut is missing, worn or stripped
- Straightforward to fit with basic hand tools; no modifications required
- New old stock: may show light tarnish or storage marks that do not affect use
- Period-correct part that supports authentic restoration of classic Villiers engines
Typical Applications:
Used during carburettor rebuilds and services on Villiers engines to lock the mixture needle after tuning.
