Description
Overview:
The Villiers No 42 Main Jet for the B10/2 carburettor is a genuine OEM fuel metering jet designed to restore correct mixture on classic engines using Villiers carburettors. Precision-drilled from solid brass for corrosion resistance and consistent flow, it governs fuel delivery through the main circuit at mid to full throttle. This makes it a key service part for keeping vintage machinery running smoothly and efficiently. Engineered specifically for the Villiers B10/2 carburettor and supplied as unused old stock, it may show light tarnishing from age that does not affect performance. Identified by Manufacturer Part Number (MPN) V1544 and marked as size 42, it is a direct replacement for a worn, blocked or incorrect jet on period engines found in lawn mowers, stationary engines and small agricultural or horticultural equipment.
Key Features:
- Genuine Villiers OEM part for assured fit and fuel calibration on B10/2 carburettors
- Size 42 main jet for correct mid-high throttle fuel metering and engine response
- Brass construction resists corrosion from modern petrol and ensures stable orifice size
- Direct replacement design for straightforward servicing and set-up
- Helps cure common running issues linked to incorrect mixture (hesitation, plug fouling, flat spots)
- Unused old stock; cosmetic tarnish may be present but has no functional impact
- Typically installs with basic hand tools; always check float bowl cleanliness before fitting
- Supports reliable starting, clean acceleration and consistent power on classic machinery
Typical Applications:
Used during carburettor overhaul or tuning on vintage equipment fitted with Villiers B10/2 units, including classic lawn mowers, small stationary engines, cultivators and horticultural machines. Suitable where accurate main-circuit fuelling is needed to maintain smooth running, prevent lean surging, and optimise fuel economy on period petrol engines.
