  If the Husqvarna Lawn Mower engine doesn't start, it could be due to several reasons. First, ensure there is fuel in the fuel tank and refill if necessary. A faulty spark plug, defective ignition cable, or dirt in the carburettor or fuel line can also prevent starting; in these cases, replace the spark plug or ignition cable, or clean the carburettor and fuel line. Also, the starter motor might not be turning over the engine, so inspect it. Finally, a defective safety switch can cause this issue, so check, repair, or replace the safety switch.

  If your Husqvarna Lawn Mower engine isn't running smoothly, several factors could be responsible. A faulty spark plug could be the culprit, so replace it.

  If your Husqvarna Lawn Mower isn't mowing evenly, it could be due to several factors. Dull blades could be the issue, so sharpen them. Avoid mowing long or wet grass; mow when the grass is dry and at an appropriate length. Check if the cutting unit is askew and adjust it. Also, ensure there's no grass blockage under the hood and remove any if present. Unequal tyre pressures can also cause uneven mowing, so equalize the tyre pressures on both sides. Finally, reduce the mowing speed if you are over-speeding.

  If the starter motor on your Husqvarna Lawn Mower doesn't turn over the engine, it could be due to a few reasons. The battery might be flat, so try charging or replacing it. Ensure there's a good connection between the cable and the battery. Also, check the lift lever for the cutting unit to ensure it's in the correct position and verify that the brake is activated. A blown main fuse or a faulty ignition lock could also be the cause, so replace the fuse or repair/replace the ignition lock. Finally, the starter motor itself might be faulty, requiring replacement.
