Description
Overview:
The Pilot Jet for Villiers B10/1 Carburettor (OEM reference 28103) is a small but essential metering component used in the idle/low‐speed circuit of Villiers carburettors. Made from precision‐machined brass for reliable fuel resistance and long service life, it regulates the fuel‐air mixture at idle and during gentle throttle openings. This ensures easier starting, a steady tick‐over, and smooth pickup from low revs. Supplied as a Genuine Villiers Part, it is a direct fit for the Villiers B10/1 and B101 carburettors found on many vintage lawn and garden machines and small industrial engines. As unused old stock, it may show light tarnishing from age, which does not affect performance, making it a practical and authentic choice for restoration and maintenance work.
Key Features:
- Genuine Villiers Part for assured fit and function (OEM 28103)
- Brass construction for corrosion resistance and stable metering with petrol
- Precisely drilled orifice for consistent fuel flow in the pilot circuit
- Helps cure poor idling, stalling, and hesitation off idle
- Direct replacement for Villiers B10/1 and B101 carburettors
- Suitable for vintage restorations; unused old stock with possible light tarnish only
- Straightforward installation during routine carburettor service or rebuild
- Supports smoother starting, steady idle speed, and cleaner throttle response
- Durable, serviceable part designed to OEM specification
- Clear identification by Villiers reference 28103
Typical Applications:
Used when servicing or rebuilding Villiers B10/1/B101 carburettors on classic lawnmowers, stationary engines, rotavators, and light construction or horticultural equipment. Commonly fitted to resolve erratic idle, hunting, or bogging when the throttle is first opened. Ideal for preventative maintenance on restored or infrequently used machines to maintain reliable low‐speed running.
