Key Features
- OEM-Calibrated Fuel Metering — Built to Husqvarna's exact air-to-fuel ratio specifications, delivering the precise mixture these power cutter engines require for consistent throttle response and power output.
- Exact-Match Replacement — Engineered to match the original carburettor's port sizing, mounting dimensions, and fuel inlet connections for a direct installation on compatible machines.
- Confirmed Fitment — Compatible with the K650, K700, and K650CutnBreak power cutters; cross-reference 506321503 against your parts diagram before ordering to confirm applicability to your specific unit.
- Restored Engine Performance — A worn or deteriorated carburettor causes hard starting, rough idling, and loss of cutting power; replacing it with this genuine OEM unit brings engine response back to original operating condition.
- Fuel System Integrity — Genuine OEM construction ensures all seals, needle seats, and diaphragm interfaces meet Husqvarna's standards, reducing the risk of fuel leaks and associated fire hazards on an active cut-off saw.
The carburettor is the component responsible for blending air and fuel in the correct ratio before delivering the mixture to the engine's combustion chamber. On a power cutter like the K650 or K700, precise fuel metering is critical — too lean a mixture causes overheating and loss of power, while too rich a mixture leads to fouled spark plugs, excessive smoke, and poor cutting performance. When a carburettor wears, warps, or its internal components degrade, the engine becomes difficult to start, runs inconsistently, or stalls under load; replacing it with a correctly spec'd unit restores full, reliable engine operation.
