What to do if Murray Lawn Mower engine will turnover but will not start?
- J
  Janet McdowellAug 5, 2025
  If your Murray Lawn Mower engine turns over but doesn't start, the issue could stem from several causes related to the choke and fuel. If the engine is cold, ensure the choke is in the CLOSED position. If the engine is warm, the choke should be in the OPEN position. If the engine is flooded, set the choke to OPEN when cranking. Check the fuel level; if it's empty, let the engine cool before refilling. Old or stale fuel can also prevent starting, so drain it and replace it with fresh fuel. Lastly, inspect the spark plug(s) for faults, fouling, or incorrect gapping, and clean, gap, or replace them as necessary. If the problem persists, the safety interlock switch may be faulty, and you should contact your local authorized dealer for replacement.

Why Murray E20M42 engine will not turnover?
- A
  Ashley DavisAug 9, 2025
  If your Murray Lawn Mower's engine won't turnover, several factors could be at play. First, make sure the ignition switch is fully turned to the START position and the ground speed levers are set to START/PARK. Ensure the mower blade switch is in the OFF position and the parking brake lever is in the ENGAGE position. Check the battery terminals and clean them if necessary. Your battery might be discharged or dead, so try recharging or replacing it. Inspect the wiring for any loose or broken connections, and tighten or replace them as needed. If these steps don't resolve the issue, the safety interlock switch, solenoid, or starter motor may be faulty, and you should contact your local authorized dealer for replacement.

How to fix Murray E20M42 that starts hard or runs poorly?
- R
  Regina LinAug 15, 2025
  If your Murray Lawn Mower engine starts with difficulty or runs poorly, start by checking the air filter, as a plugged filter can cause this issue. Service the pre-cleaner and/or replace the air filter element. Ensure the choke is correctly set: use the CLOSED position when cranking a cold engine and switch to OPEN once the engine is running. A warm engine might not need the choke. Also, inspect the spark plug for faults, fouling, or incorrect gapping; clean, gap, or replace it as needed.

  If the exhaust from your Murray Lawn Mower engine is black, it could be due to a dirty air filter or pre-cleaner. Service or replace these as needed. Another cause could be the choke being set to CLOSED while the engine is running. Ensure you set the choke to OPEN as soon as the engine starts.
