Description
Overview:
This Genuine Stihl choke spring (part 4282 122 3005) is a small, precision-formed torsion spring made from durable spring steel. It controls the choke mechanism on Stihl backpack blowers, helping the choke plate and lever move smoothly and stay in the selected position during starting and warm-up. A sound choke spring supports reliable cold starts and stable running by keeping the choke action consistent. Designed specifically for Stihl machines such as the BR500 and BR700, it offers an exact fit with the correct preload and geometry. Ideal for routine servicing or as a direct replacement for a weak, stretched, or lost spring, it restores the original feel and function of the choke assembly without modification.
Key Features:
- Genuine Stihl part for assured compatibility and quality
- Precision-formed spring steel coil for consistent, repeatable tension
- Maintains proper choke operation to aid cold starting and smooth transition to run
- Direct fit for specified Stihl backpack blowers; no modifications required
- Compact torsion design; straightforward to install with basic hand tools
- Durable metal construction for dependable, long-term performance
- Helps prevent hard starting and erratic choke engagement caused by a fatigued spring
- Suitable for planned maintenance or quick repairs on site
Typical Applications:
Used during carburettor servicing, choke shaft or lever replacement, and general maintenance of Stihl backpack blowers. Replace when the choke lever will not hold position, returns poorly, or when starting performance declines due to a weakened or missing spring. Also useful after disassembly where the original spring is damaged or lost.
