Description
Overview:
The Main Jet - Robin Part - RB129 62400 08 is a precision component for carburettors on small petrol engines used in construction and garden machinery. Typically made from precision‐machined brass for long service life, the main jet meters fuel to the engine at mid to high throttle, helping maintain clean combustion, steady power and reliable running. It is suited to equipment such as generators, water pumps, plate compactors, lawn mowers and small tillers commonly powered by Robin small engines. Fitting a sound main jet is an effective way to restore correct fuelling where engines hesitate, surge or run lean under load. This part supports routine servicing and repair work, keeping equipment dependable on site and in the garden.
Key Features:
- Precision metering for consistent fuel delivery at working speeds and load
- Durable brass construction to resist wear and corrosion from standard pump fuels (including E5)
- Helps restore smooth acceleration, stable running and efficient combustion
- Supports easier starting and reduces the likelihood of plug fouling when the carburettor is set correctly
- Manufactured to meet original equipment performance tolerances for flow and fit
- Compact, simple form factor for straightforward installation using basic hand tools
- Suitable for servicing and preventative maintenance on small Robin engine carburettors
- Reliable choice for daily‐use equipment exposed to dust and vibration on site
- Identified by reference RB129 62400 08 for easy parts selection and inventory control
- Can assist accurate tuning when paired with correct pilot jet and float settings
Typical Applications:
Used during carburettor overhauls or routine services on small engines powering generators, pumps, compactors, mixers, mowers, scarifiers and similar equipment. Ideal where engines run weak at mid‐range, struggle under load, or show poor fuel economy due to an incorrectly sized or worn main jet.
Also known as:
Carburettor main jet, main metering jet, fuel main nozzle, primary jet, carb main fuel jet, main fuel orifice, main circuit jet.
