Description
Overview:
This Spring for Throttle Stop Screw is a genuine Villiers part for Zenith 24T-2 carburettors (MPN 04611). It is a precisely wound metal spring that provides the correct return force on the throttle stop screw, helping you set and maintain a stable idle and predictable throttle response. Used on classic small engines such as the Villiers MK20 and MK25, it supports accurate carburettor adjustment and preserves the intended behaviour of vintage equipment. Built for reliability, it replaces worn or weakened springs that can lead to erratic idle, stalling, or poor pick‐up. A like‐for‐like replacement, it fits directly on the stop screw assembly of the carburettor, restoring proper control and preserving authenticity on period machinery.
Key Features:
- Genuine Villiers part (MPN 04611) for correct fit and function
- Designed specifically for Zenith 24T-2 carburettors to stabilise idle and throttle position
- Durable metal construction resists set and fatigue during regular use
- Helps achieve steady idle speed and smoother pick‐up after rebuilds or servicing
- Consistent spring pressure supports reliable carburettor adjustment and repeatable settings
- Simple like‐for‐like replacement that locates over the throttle stop screw
- Suitable for vintage restoration where originality and compatibility matter
- Trusted on classic Villiers and JAP engines used in machinery and stationary plant
Typical Applications:
Used during carburettor overhaul or routine servicing to restore precise throttle stop control on classic engines. Common on vintage mowers, rotavators, generators, pumps, cement mixers, and other stationary plant using Zenith 24T-2 carburettors. Ideal for resolving drifting idle speed, hunting, or inconsistent throttle response caused by a tired or missing stop screw spring.
