In this article, we’ll walk you through the most common reasons why your engine won’t start and provide easy steps to fix it.

Common Reasons Why Your Murray Lawn Mower Engine Won’t Start & Fixes

Here are some of the possible causes of Murray lawn mower engine failure and how to address them:

1. Lack of Fuel or Stale Gasoline

The first thing to look at when your mower is not starting is the fuel. If the fuel is old, it may contain some sediments that may clog the carburetor and hinder the engine from starting. Also, it is obvious that an empty tank will not allow your mower to run.

How to Fix:

  • Check the Fuel Level: Make sure that fresh fuel is in the fuel tank if it is empty. Use premium, fresh fuel at all times.

  • Replace Stale Fuel: If the gasoline in your mower has been stagnant for more than 30 days, then it is advisable to empty the tank and refill it with fresh gasoline.

  • Add Fuel Stabilizer: If you are going to store your mower for a long time, it is advisable to add a fuel stabilizer to the fuel.

2. Dirty or Worn Spark Plug

A dirty or worn spark plug is one of the most common reasons for starting problems. Spark plugs become coated with carbon and dirt and this makes them incapable of producing the necessary spark.

How to Fix:

  • Examine the spark plug:  Here, one needs to remove the spark plug from the engine and ascertain  its condition in terms of the degree of wear, dirt or carbon deposits.

  • Clean or Replace the Spark Plug: Set up a wire brush or spark plug cleaner to eliminate any dirt from the spark plug. It ought to be replaced with a new one if it is worn out or broken.

  • Spark Plug Gap: Make sure that the gap between the electrodes of the spark plug is set to the manufacturer’s recommended size, which can be found in the owner’s manual.

3. Clogged Carburetor

The carburetor is the device that blends the air and fuel before it gets into the engine.The combustion chamber will have trouble starting if the engine's carburetor is unclean or clogged with dirt or leftover fuel.

How to Fix:

  • Drain the Carburetor: If you think that the carburetor is full of fuel, then it is advisable to drain the old fuel from the carburetor and the fuel lines.

  • Clean the Carburetor: To ensure that the carburetor jets are free from any debris, clean the carburetor using a carburetor cleaner. If you are in doubt, it is advisable to seek the services of a professional mechanic to clean or rebuild the carburetor.

4. Faulty Safety Features or Switches

Murray lawn mowers have safety features such as switches that help to avoid accidental starting of the machine or causing harm on the operator. If any of these switches is faulty, it may hinder the engine from starting up as expected.

How to Fix:

  • Check Safety Switches: Make sure that the safety lever on the handle and any other switches are in the safe position. If you are using a self-propelled model, make sure that the drive system is in the ‘off’ position.

  • Inspect the Blade Brake: The combustion chamber will have trouble starting if the internal combustion engine is unclean or clogged with dirt or leftover fuel. If it is defective, then it may require replacement.

5. Dead or Weak Battery (For Electric Start Models)

If your Murray lawn mower has an electric start and the engine is not turning over, it is possible that the battery is dead or low on charge. A weak battery can also hinder the engagement of the starter motor.

How to Fix:

  • Check the Battery: Start the test by checking the battery charge level to make sure that they are fully charged. If it is low or dead, then it should be recharged.

  • Replace the Battery: If the battery is not holding charge then it may require replacement.

6. Fuel Shutoff Valve is Closed

Some Murray lawn mowers have a fuel shutoff valve that can be accidentally turned off to stop the flow of fuel to the engine.

How to Fix:

  • Identify the Fuel Shutoff Valve: The fuel shutoff valve is generally situated close to the fuel tank or the carburetor.

  • Ensure It’s Open:  Ensure that the valve is in the open position to allow the fuel to flow to the engine.

A Murray lawn mower engine that will not start can be quite infuriating but the good news is that most of the problems can be solved by following some simple procedures. To avoid such issues in the future, you should ensure that you use fresh fuel and check your spark plug among others. Murray lawn mower parts are available for purchase to ensure that your mower is always in top condition and ready to provide you with the performance you need for years to come.
