  Teresa WardAug 17, 2025
  If your Jonsered Lawn Mower is hard to start, it could be due to several reasons. The air filter might be dirty, requiring cleaning or replacement. The spark plug could be bad and need replacing. The battery might be weak or dead, so try recharging or replacing it. A dirty fuel filter could also be the culprit, in which case, replace it. Stale or dirty fuel necessitates draining the tank and refilling with fresh gasoline. Check for loose or damaged wiring. If these steps don't resolve the issue, the carburetor may be out of adjustment, or the engine valves may need adjustment by an authorized service center.
