Troubleshooting Common Bolens Lawn Mower Problems
1. My Bolens Won’t Start:
a. Fuel Problems:
- Check for a Fuel Shortage: The most common reason a lawn mower won’t start is simply running out of gas. Add fresh fuel to the tank and try starting again.
- Examine the Fuel Lines: Ensure the fuel lines are connected securely and free from cracks or leaks.
- Clean the Fuel Filter: A clogged fuel filter can restrict fuel flow. Replace it if necessary.
- Verify the Fuel Valve is Open: Make sure the fuel valve is open, allowing fuel to reach the carburetor.
b. Ignition Issues:
- Inspect the Spark Plug: Remove the spark plug, inspect it for damage or carbon buildup, and clean or replace it if necessary.
- Test the Spark Plug: Connect the spark plug to the spark plug wire and hold it near a grounded metal object. When you crank the engine, a bright blue spark should jump between the electrodes. If there is no spark, the ignition system may have a problem.
- Examine the Spark Plug Wire: Inspect the spark plug wire for cracks, fraying, or loose connections.
c. Air Filter Issues:
- Check the Air Filter: A dirty air filter can restrict airflow to the engine, making it difficult to start. Clean or replace the filter.

b. Deck Height Issues:
- Adjust the Deck Height: Make sure the cutting deck is set to the desired height for your lawn.
c. Mowing Technique:
- Overlapping Mowing Passes: Overlap each mowing pass by about one-third of the mower’s width to ensure even cutting.
3. My Bolens Engine is Smoking or Leaking:
a. Oil Problems:
- Check the Oil Level: Overfilling the crankcase can cause excessive oil consumption and smoking.
- Change the Oil Regularly: Follow the manufacturer’s recommended oil change schedule to keep the engine clean and prevent premature wear.
- Examine the Oil Filter: A clogged oil filter can lead to oil leaks and engine damage.
b. Fuel Problems:
