  If your Jonsered Lawn Mower is hard to start, consider these possible causes: a dirty air filter (clean or replace it), a bad spark plug (replace it), a weak or dead battery (recharge or replace it), a dirty fuel filter (replace it), or stale fuel (empty the tank and refill with fresh gasoline). Also, check for loose or damaged wiring. If these steps don't help, the carburetor or engine valves may need adjustment by an authorized service center.

  If your Jonsered Lawn Mower won't start, several factors could be at play. It might be as simple as being out of fuel; in that case, fill the fuel tank. Ensure the engine is properly choked following the instructions in the Operation section. If the engine is flooded, wait a few minutes before trying again. Other potential issues include a bad spark plug (replace it), a dirty air filter (clean or replace it), a dirty fuel filter (replace it), or water in the fuel (empty the fuel tank and carburetor, refill with fresh gasoline, and replace the fuel filter). Also, check for loose or damaged wiring. If none of these resolve the issue, the carburetor or engine valves may need adjustment, and you should seek assistance from an authorized service center.

Why is my Jonsered LT2218CMA losing power?
- S
  sharonsmithAug 23, 2025
  Loss of power in your Jonsered Lawn Mower can stem from several causes. You might be cutting too much grass or moving too fast, so raise the cutting height and reduce your speed. Ensure the throttle isn't in the “CHOKE” position. A build-up of grass under the mower, a dirty air filter, low or dirty oil, a faulty spark plug, a dirty fuel filter, or stale fuel could also be culprits. Check for a loose spark plug wire and clean any debris from the engine air screen/fins. A dirty or clogged muffler can also cause power loss. Finally, inspect all wiring and, if necessary, have the carburetor or engine valves adjusted by a qualified service center.

- J
  James MoyerAug 28, 2025
  If the engine of your Jonsered Lawn Mower will not turn over, make sure the brake pedal is depressed and the attachment clutch is disengaged. Other potential causes include a weak or dead battery (recharge or replace it), a blown fuse (replace it), corroded battery terminals (clean them), or loose or damaged wiring (check all wiring). A faulty ignition switch, solenoid, starter, or operator presence switch could also be the issue. For these more complex components, you may need to contact an authorized service center.

How to improve grass discharge on Jonsered LT2218CMA?
- J
  jgarrisonAug 30, 2025
  Poor grass discharge from your Jonsered Lawn Mower could be due to several factors. Ensure the engine speed is set to “FAST” and you're not traveling too quickly; shift to a slower speed. Wet grass can also cause this issue, so allow the grass to dry before mowing. Check that the mower deck is level and the tires have proper air pressure. Other causes include a worn, bent, or loose blade (replace or sharpen it and tighten the bolt), a buildup of grass under the mower (clean the underside), a worn mower drive belt (replace it), improperly installed blades (reinstall them with the sharp edge down), using improper blades (replace with the correct ones), or clogged mower deck vent holes (clean around the mandrels).

Why is my Jonsered LT2218CMA Lawn Mower cutting unevenly?
- S
  Sharon NelsonSep 1, 2025
  Uneven cutting with your Jonsered Lawn Mower can result from a worn, bent, or loose blade (replace the blade and tighten the bolt). Also, the mower deck may not be level (level the mower deck). Buildup of grass under the mower (clean the underside), a bent blade mandrel (replace the blade mandrel), or clogged mower deck vent holes (clean around the mandrels) can also cause an uneven cut.
