Why is my Husqvarna 325L engine hard to start?
- JJohn HuntAug 13, 2025
A hard-to-start Husqvarna Trimmer engine can be caused by several factors related to fuel and carburetor function. These include a stop screw for the throttle that doesn't operate correctly, a blocked fuel filter or fuel hose, air in the fuel pipes, incorrect fuel, a defective needle valve, a damaged or improperly operating lever arm of the needle valve, a damaged control diaphragm or one with a defective seal, a blocked or worn needle valve, or an object in the needle valve guide.
