Description

The Fixed Jet 0.66 is a genuine Stihl carburettor component that meters fuel accurately for stable running on selected professional chainsaws and cut-off saws, including the MS440D and MS460R. Precision‐machined from durable brass, it provides a fixed fuel flow calibrated to Stihl specifications, helping to maintain the correct fuel‐to‐air ratio under load and at high revs. This jet is suitable for two‐stroke engines where consistent fuelling is essential for clean starting, smooth acceleration, and full‐power cutting performance. As an OEM part (MPN: 1128 121 5605), it is built to match the original fit and function, making it a reliable choice for routine servicing, carburettor rebuilds, and resolving fuelling issues on compatible Stihl machines. Genuine Stihl part for assured compatibility and longevity.

– Brass construction for strength, stability, and corrosion resistance
– Fixed 0.66 calibration for consistent fuel metering across the rev range
