  The engine might not start due to several reasons. There may be no fuel, so refill the fuel tank. A faulty spark plug could be the culprit, so replace it. Inspect and replace a defective ignition cable. Also, the carburettor or fuel line could be dirty, requiring cleaning. Check and repair the starter motor if it doesn't turn over the engine. Finally, a defective safety switch may be the cause, so check and replace it.

  If the starter motor on your Jonsered Lawn Mower isn't turning the engine over, several factors could be at play. Ensure the parking brake is engaged. Also, make sure the cutting deck lift lever isn't in the mowing position. A blown main fuse, a poor connection between the cable and battery, or a weak battery can also prevent the starter motor from working. In these cases you should replace the main fuse or charge the battery. Finally, the starter motor itself might be defective.

  If the engine isn't running smoothly, it could be due to a faulty spark plug, which should be replaced. The carburettor might be incorrectly set and needs adjustment. A clogged air filter can also cause this issue, so clean or replace it. Check for a blocked fuel tank vent and clear it if necessary. Other potential causes include a defective ignition key (replace it), dirt in the carburettor or fuel line (clean them), or a choking/incorrectly adjusted throttle cable (adjust or repair it).
