Essential Pre-Start Checks
Before attempting to start your gas lawn mower, perform these essential checks:
- Check the Fuel: Ensure your mower has fresh fuel. Old fuel can cause starting issues. If the mower has been sitting for several months, drain the old fuel and replace it with fresh gasoline.
- Inspect the Oil Level: Check the oil level using the dipstick. If it’s low, add the appropriate type of oil as specified in your owner’s manual.
- Examine the Spark Plug: Remove the spark plug and inspect it for wear or carbon buildup. Clean or replace the spark plug if necessary.
- Clean the Air Filter: A dirty air filter can hinder performance. Remove it and clean or replace it, depending on its condition.
Steps to Start Your Gas Lawn Mower
Once you’ve completed the pre-start checks, follow these steps to start your mower:
- Set the Choke: If your mower has a choke lever, set it to the “choked” position. This helps deliver the right fuel-air mixture.
- Turn the Fuel Valve On: Ensure the fuel valve is in the “on” position if your mower has one.
- Prime the Engine: Press the primer bulb (if equipped) several times until you see fuel in the bulb. This is typically about 3-5 presses.
- Pull the Starter Cord: Stand firmly, ensuring you have a good grip. Pull the starter cord swiftly until the engine starts. If it doesn’t start after a few pulls, check the choke and fuel supply.
Common Starting Issues and Troubleshooting
If your mower still won’t start, consider these common issues:
- Fuel Problems: If the fuel is old or contaminated, replace it with fresh gasoline. Consider adding a fuel stabilizer like STA-BIL to prevent future issues.
- Battery Issues: For electric start mowers, ensure the battery is charged. Replace it if it’s old or not holding a charge.
- Clogged Air Filter: A clogged air filter can prevent proper airflow. Clean or replace it as needed.
- Faulty Spark Plug: A worn spark plug can prevent starting. Replace it if it appears damaged.

What should I do if my gas lawn mower won’t start?
Start by checking the fuel, oil level, and spark plug. Clean or replace parts as needed. If problems persist, consult the owner’s manual or a professional.
How often should I service my gas lawn mower?
Routine maintenance is key. Check oil levels before each use, replace the air filter every 25 hours of operation, and service the spark plug annually.
Can I use old fuel in my lawn mower?
Using old fuel can lead to starting issues and poor performance. Always try to use fresh fuel, ideally less than 30 days old.

Regular maintenance, using quality fuel, and proper storage practices can significantly extend the lifespan of your mower.
