Description
Overview:
The Husqvarna choke shaft is a precision-machined metal component that links the choke control to the carburettor's air shutter. Its job is to regulate air flow during cold starts and warm-up, helping the engine fire quickly and run smoothly. Built for regular use in construction and garden machinery, it offers a stable, wobble-free rotation and dependable alignment with the choke plate. The robust material and tidy tolerances make it suitable for saws, power cutters, brushcutters and similar equipment. It is commonly identified by Husqvarna codes 505 31 66 02 and 505316602, making it straightforward to match during servicing. A good choke shaft helps reduce hard starting, improves idle quality, and supports consistent performance across varied working conditions.
Key Features:
- Precision-machined metal shaft for smooth choke actuation and consistent air control
- Durable construction to withstand vibration, fuel exposure and frequent use
- Stable fit in the carburettor body to minimise play and wear at pivot points
- OEM-spec dimensions for reliable alignment with choke plate and linkages

Typical Applications:
Used when refurbishing or repairing the choke mechanism on Husqvarna machinery with carburettors, including chainsaws, cut-off saws/power cutters, brushcutters, and similar outdoor power equipment. Suitable for workshop servicing and on-site maintenance where reliable cold starts and stable idle are important for daily operation.
