Husqvarna 455 Rancher 55.5 cc 3.5 HP Gas Chainsaw with X-Torq Engine and Air Injection DIES AT IDLE Error Fix: Engine Dies When Idling

The engine starts but stalls when returning to idle speed — the carburetor idle mixture (LA screw) needs adjustment; on Husqvarna chainsaws the LA screw is usually accessible with a screwdriver and controls idle speed; turn it clockwise to increase idle rpm until the engine idles smoothly without the chain moving (chain should NOT move at idle); a clogged fuel filter, cracked fuel line, or dirty carburetor can also cause idle problems; if the carburetor has been sitting with old fuel, it may need cleaning or rebuilding
