Description
Overview:
The Revers Mainjet 107.5 is a precision-machined carburettor main jet for small petrol engines, sized to deliver accurate fuel metering under load. Built from durable metal for long service life, it regulates fuel flow at mid to full throttle, helping the engine start reliably, pull cleanly, and run efficiently. This jet is intended for the Robin EY35 engine, commonly found in garden and construction machinery such as compactors, generators, mixers, and pumps. The 107.5 marking identifies the metering size used by the carburettor design. A correct, unworn main jet is essential for maintaining performance, reducing hesitation, and achieving stable combustion, especially after routine servicing or when restoring an engine that has suffered from varnish, wear, or contamination.
Key Features:
- Precision size 107.5 for consistent fuel delivery and stable running
- Robust metal construction for long-lasting use in demanding environments
- Helps restore power, throttle response, and fuel efficiency when replacing a worn jet
- Clean, accurate metering to support easier starting and smoother acceleration
- Direct-fit compatibility with the Robin EY35 carburettor to minimise downtime
- Smooth internal finish to promote steady fuel flow and reliable tuning
- Suitable for routine servicing, rebuilds, and preventative maintenance
- Simple to install with standard hand tools as part of a carburettor service
Typical Applications:
Used in small engines powering construction and garden equipment where the Robin EY35 is fitted, including plate compactors, generators, water pumps, concrete mixers, and similar machinery. Ideal when addressing poor running, surging, flat spots, or fuel-related performance issues after storage. A suitable replacement during carburettor overhauls, especially when jets are blocked, worn, or damaged.
Also known as:
Carburettor metering jet, fuel metering jet, main fuel jet, main nozzle, carb jet, main circuit jet. These terms refer to the same component responsible for controlling fuel flow through the carburettor's main circuit at mid to high throttle.
