Description
Overview:
This Main Jet Assembly is a genuine Villiers part for the B1320 carburettor (OEM No. 25709). Made from precision‐machined brass for long service life and corrosion resistance, it controls fuel flow through the carburettor's main circuit to keep the engine running smoothly under load. It is suitable for Villiers carburettors on small engines used in garden and light construction equipment, including models such as B1320 and C45. As an unused old‐stock vintage item, it may show light tarnishing or cosmetic age without affecting performance. Designed as a direct replacement for the original jet assembly, it helps restore correct fueling and consistent engine behaviour on well‐maintained Villiers-powered machinery.
Key Features:
- Genuine Villiers part for correct fit and function
- OEM No. 25709 for direct like‐for‐like replacement
- Brass construction for durability and fuel resistance
- Precision metering for stable idle, acceleration, and top‐end running
- Helps address lean running, hesitation, and poor throttle response when the original jet is worn or blocked
- Compatible with listed Villiers carburettor models including B1320 and C45
- Suitable for maintaining and restoring vintage equipment while keeping originality
- Unused old stock; minor tarnish possible, performance unaffected
- Straightforward installation using standard hand tools
- Reliable operation when paired with clean fuel and a sound filtration system
Typical Applications:
Used in Villiers carburettors on lawn mowers, rotavators, stationary engines, generators, small pumps, and compact light‐plant where stable fuel delivery is required. Ideal for routine servicing, fault finding on poor running, and sympathetic restoration of vintage machinery that relies on accurate main‐circuit metering.
Also known as:
Main fuel jet, main metering jet, main jet nozzle, carb jet assembly, fuel metering nozzle, main circuit jet.
