Description
Overview:
The Main Jet for Villiers A15 Sloper Engines (ref 31126) is a precision-machined brass fuel metering component used in Villiers carburettors. As a Genuine Villiers Part, it is designed specifically for the B10/1 carburettor and A15 sloper engine layouts, where it controls the fuel flow at mid to full throttle for stable running and clean pick-up. Correct jetting helps avoid lean running, misfires, and excessive fuel use. This unused old stock item retains original factory specification and tolerances, while minor age-related tarnishing is normal for vintage parts and does not affect function. Suitable for tradespeople restoring classic machinery and DIY users maintaining working engines, it provides an authentic, direct-fit solution that helps return engines to reliable, predictable operation.
Key Features:
- Genuine Villiers part for assured fit and performance on A15/B10/1 applications
- Precision-drilled brass jet for consistent fuel metering and smooth running
- Direct screw-in replacement for the B10/1 carburettor; straightforward to fit with basic tools
- Helps restore correct air-fuel ratio under load, aiding starting, acceleration, and economy
- Suitable for routine maintenance, overhaul, or period-correct restoration work
- Unused old stock (NOS) with original specification; may show light tarnish from storage
- Durable construction resists corrosion from petrol and normal operating temperatures
- Supports stable idle-to-throttle transition and reduces flat spots when correctly tuned
- Compatible with unleaded petrol and standard carburettor cleaning methods
- Clear identification (31126) to aid matching during service and parts cataloguing
Typical Applications:
Used in Villiers A15 sloper engines fitted to small plant, stationary equipment, light construction machinery, and vintage garden machines. Ideal when rebuilding carburettors, correcting poor running or high fuel use, or replacing worn or damaged jets to return engines to dependable everyday service.
