Description
Overview:
This Genuine Stihl carburettor HD-19C is a direct replacement for the fuel system on selected Stihl petrol chainsaws, including the MS290 and MS310. Built with a robust die-cast aluminium body and precision internal components, it meters the air-fuel mixture accurately for reliable starting, smooth idling, and strong acceleration under load. As a diaphragm-type unit, it performs consistently in varied positions and conditions, making it well suited to forestry and site work. It is designed to bolt straight on in place of the original unit (OEM reference 1127 120 0650), using the existing throttle and choke linkages. A sound carburettor restores performance and reduces poor running caused by wear, varnish, or damaged diaphragms, helping your saw cut cleanly and efficiently.
Key Features:
- Genuine Stihl part for assured fit and compatibility
- Die-cast aluminium construction for durability and corrosion resistance
- Diaphragm design maintains consistent fuelling in any working position
- Precise metering for stable idle and clean pick-up across the rev range
- Direct-fit replacement using original mounting points and linkages
- Suitable for routine tuning with standard H, L and idle (LA) adjustments
- Helps restore cutting performance and fuel efficiency on ageing saws
- Built to work with standard unleaded pump fuel used in 2‐stroke mixes
Typical Applications:
Used on mid-range Stihl chainsaws for general forestry, farm, and landscaping tasks. Ideal for felling small to medium timber, cross-cutting, firewood processing, site clearance, and grounds maintenance. A good choice when a saw is hard to start, won't hold tune, bogs on throttle, or shows erratic idling due to a worn or contaminated carburettor.
