Description
Overview:
This genuine Husqvarna low-speed needle (OEM No. 502 10 29 01) is a precision carburettor component for selected petrol machines, including the 240R and 245R brushcutters. Manufactured from corrosion-resistant brass with a finely tapered tip and threaded shank, it meters fuel on the idle/low-speed circuit to keep the engine stable at tickover and during gentle throttle inputs. Replacing a worn or damaged needle restores accurate mixture control, improving cold starting, smooth idle, and clean pick-up from low revs. Designed specifically for Husqvarna two-stroke equipment, it fits directly into the original carburettor with no modification. As a genuine part, it matches factory dimensions and sealing points for dependable performance and long service life in demanding grass cutting, clearing, and maintenance work.
Key Features:
- Genuine Husqvarna part for assured compatibility and reliability
- OEM reference 502 10 29 01 for precise identification and fit
- Precision-tapered needle for accurate fuel metering at idle and low RPM
- Durable brass construction resists corrosion and modern petrol blends
- Fine thread allows controlled, repeatable adjustment during tuning
- Direct replacement; straightforward to install with basic hand tools
- Helps stabilise idle, reduce stalling, and improve throttle response
- Engineered for Husqvarna carburettors used on 240R/245R/245RX/36
- Supports efficient running and fuel economy when correctly tuned
Typical Applications:
Used during carburettor servicing, rebuilds, or tuning to restore proper low-speed mixture control. Ideal when the original needle is worn, bent, or corroded, causing hard starting, erratic idle, or hesitation. Suitable for professional grounds maintenance, commercial landscaping, and domestic garden work where consistent, smooth low-speed performance is needed.
