Description
Overview:
The Main Jet #62 is a genuine Honda OEM component for the Honda GX120 petrol engine, supplied under part number 99101-ZK7-0620. Precision‐machined from durable brass, it meters fuel through the carburettor's main circuit to maintain the correct air-fuel ratio under load and at higher throttle openings. This helps the engine run smoothly, start reliably, and deliver consistent power while keeping fuel use efficient. It is a direct fit for Honda GX120 equipment and selected machines such as the WB20XT water pump, making it suitable for compact generators, small construction tools, and light industrial machinery that rely on the GX120 power unit. Built to Honda specifications, it is a straightforward swap during routine servicing or when resolving running issues caused by a worn or clogged jet.
Key Features:
- Genuine Honda part for assured fit and compatibility with GX120 carburettors
- Precision‐calibrated #62 orifice for accurate fuel metering and stable performance
- Brass construction resists corrosion and wear for long service life
- Supports smooth acceleration, steady running under load, and reliable hot/cold starts
- Helps maintain fuel efficiency and reduce hesitation or surging
- Direct replacement with OEM dimensions for easy installation and minimal downtime
- Manufactured to Honda tolerances for consistent, repeatable tuning outcomes
- Suitable for routine maintenance or troubleshooting poor running caused by jet blockage
Typical Applications:
Used during carburettor servicing on Honda GX120 engines found on compact generators, plate compactors, water pumps (including WB20XT), small mixers, and similar equipment. Ideal when restoring performance after fuel contamination, addressing lean or rich running, or replacing a damaged or worn main jet to return the engine to factory fuelling.
Also known as:
Main nozzle, metering jet, carb main jet, fuel metering nozzle. These terms refer to the same carburettor component that controls main‐circuit fuel flow at mid to high throttle.
