Description
Overview:
The Main Jet No. 34 for Villiers B10/2 carburettors is a genuine Villiers part made from durable brass to deliver accurate fuel metering in the main circuit. This jet is sized "34" to suit the B10/2 carburettor, helping maintain the correct air-fuel ratio for reliable running and clean combustion on classic small engines. Typical applications include vintage stationary engines, mowers, and horticultural or workshop equipment fitted with the Villiers B10/2. Supplied as unused old stock (NOS), the jet may show light tarnishing from age, but this does not affect performance. Its robust brass construction resists corrosion and wear, making it a sound choice for restoration, servicing, and keeping period machinery operating as intended. Genuine Part status provides confidence in fit and function.
