Description
Overview:
The carburettor is a complete replacement fuel-mixing unit for Husqvarna two‐stroke petrol chainsaws, built to restore smooth running and reliable starting. It meters the correct air-fuel ratio across idle, mid‐range and full throttle to keep the engine stable under load. The main body is a robust die‐cast aluminium alloy with fuel‐resistant polymer fittings and brass metering components for durability. It is suitable for popular professional saws such as the Husqvarna 372XT and 365XT, where clean, consistent tuning is essential for cutting performance. Supplied to match the original specification (OEM reference 531 43 97‐01), it replaces earlier numbering where applicable and accepts standard linkage, intake boot and mounting screws, making it a practical choice for routine maintenance or repair without modification.
Key Features:
- Direct-fit replacement to match Husqvarna factory specification for selected 70cc-class saws
- Durable die-cast alloy body with fuel- and vibration-resistant components for long service life
- Precise metering for stable idle, crisp acceleration and strong top-end power
- Supports X‐Torq engines where listed, maintaining emissions and fuel efficiency characteristics
- Uses the original throttle, choke and impulse connections for straightforward installation
- Compatible with standard air filter, intake manifold and cylinder spacer on listed models
- Fine-adjustable mixture screws to set H, L and idle speed to local fuel and work conditions
- Helps resolve hard starting, poor throttle response, stalling and inconsistent tuning
- Replaces older part numbering for easier sourcing of the correct unit
- Suitable for professional forestry, landscaping and construction site use
Typical Applications:
Restoring reliable running on working chainsaws used for felling, snedding, logging, firewood preparation, site clearance and general grounds maintenance. Useful after long storage, contaminated fuel issues, or wear to the original carburettor causing erratic idle, bogging or over‐rich/lean running.
