Identify Reasons Why The Mantis Tiller Won’t Start

Identify Reasons Why The Mantis Tiller Won't Start

You may encounter situations where your Mantis tiller won’t start. To troubleshoot this issue, check the fuel level and ensure enough gasoline or a two-cycle oil mixture. Inspect the spark plug and clean or replace it if necessary. Also, ensure the air filter is clean and not clogged with debris.

Check the fuel lines for blockages or leaks, and turn on the ignition switch while properly positioning the throttle. If these steps don’t resolve the problem, consult the owner’s manual or contact Mantis customer support for further assistance. Remember to refer to the relevant NLP terms like spark plug, air filter, fuel line, throttle, and ignition switch while discussing these troubleshooting steps.

1. Check The Fuel

To troubleshoot a Mantis tiller that won’t start, begin by checking the fuel. Ensure that there is enough fuel in the tank and that it is not stale or contaminated. If the fuel is old or contaminated, drain it and refill the tank with fresh fuel. Inspect the fuel filter to ensure it is clean and not clogged, and replace it if necessary.

Additionally, examine the fuel line for any cracks or leaks, and replace it if needed. By checking the fuel system components, such as the fuel tank, fuel filter, and fuel line, you can address potential issues preventing your Mantis tiller from starting correctly.

2. Inspect The Spark Plug

Inspect The Spark Plug

To troubleshoot why your Mantis tiller won’t start, start by inspecting the spark plug. A common reason for starting issues is a faulty spark plug. Look at the spark plug and check if it is dirty or worn out. Use a wire brush to clean it if it’s dirty, and make sure to gap the electrode properly.

Replace a damaged or worn-out spark plug with a new one. Additionally, ensure that you securely connect the spark plug wire. If the spark plug is in good condition, you can check other potential issues, such as fuel supply, air filter clogging, or problems with the ignition system.

3. Verify The Battery

The first step is to verify the battery to troubleshoot a Mantis tiller that won’t start. Ensure that the battery is properly connected and charged. Additionally, check for corrosion on the battery terminals and clean them if necessary.

If the battery is old or damaged, it may need to be replaced. Remember also to check the fuel level and ensure fresh fuel is in the tiller. If these steps do not resolve the issue, there may be a problem with the spark plug or ignition system, which might require professional repair.

4. Examine The Air Filter

Examine The Air Filter

To troubleshoot why your Mantis tiller does not start, one possibility to consider is a clogged or dirty air filter. The air filter is crucial in allowing proper airflow into the engine. Start by removing and examining the air filter for any dirt, debris, or damage.

If you notice that the air filter is dirty, you can clean it using compressed air or simply replace it with a new one. After cleaning or replacing the air filter, reinstall it properly before starting the tiller. Further troubleshooting might be necessary if the tiller still refuses to start even after addressing the air filter.

5. Check The Oil Level

Check The Oil Level

A low oil level is one possible cause of a Mantis tiller not starting. Remove the oil cap and visually inspect the dipstick to check the oil level. If the oil level is low, add the recommended type and amount of oil as instructed by the manufacturer.

It’s important to use the correct type of oil for optimal performance. If the oil level is not the issue, there could be other reasons why the tiller won’t start, such as a clogged carburettor or spark plug issues. Remember to check these components if the oil level is not the problem.

6. Look For Loose Connections

To troubleshoot why your Mantis tiller won not start, one of the first things to check is for loose connections. Ensure all electrical connections, including the spark plug wire, are securely attached. Loose connections can disrupt the flow of electricity and prevent the tiller from starting.

Additionally, a faulty spark plug can also be the culprit. Take out the spark plug and inspect it for any damage or wear. If necessary, replace it with a new one.

Another potential cause is an issue with the fuel system. Ensure that there is enough fuel in the tank and that it is not stale or contaminated. If needed, drain the old fuel and refill it with fresh gasoline.

A clogged air filter can restrict airflow to the engine, causing starting problems. Check the air filter and clean or replace it if it appears dirty or clogged.

Inspect other mechanical components, such as the carburettor and ignition coil for any damage or wear. If necessary, have them repaired or replaced by a professional. Always consult your Mantis tiller’s manual for specific troubleshooting steps and maintenance instructions.

7. Check The Carburetor

Check The Carburetor

The carburettor is a common cause for a tiller that refuses to start. It’s possible that it could be clogged or dirty, obstructing fuel flow to the engine. To examine the carburettor, remove the air filter and check for any signs of dirt or debris. If necessary, clean or replace the air filter.

Next, take out the carburettor and use carburettor cleaner and a small brush to thoroughly clean it, paying close attention to the tiny passages and jets inside. In the event that cleaning the carburettor doesn’t resolve the issue, it might need to be replaced.

For further assistance, consult the manufacturer’s manual or contact customer support. Additionally, it’s important to inspect other components like the spark plug, fuel lines, and ignition system to ensure they are in proper working order.

8.  Check The Ignition System

When troubleshooting a mantis tiller that won’t start, it’s important to check the ignition system. This is a common culprit for starting issues. Start by removing the spark plug and grounding it against the engine. Check for a spark.

If there is no spark, it may indicate a faulty ignition coil needing replacement. Ensure that the spark plug itself is clean and properly gapped. If the ignition system is not the problem, other potential issues could include a clogged carburettor or fuel line, a dirty air filter, or a malfunctioning starter motor. By checking the ignition system first, you can narrow down the possible causes of your mantis tiller’s starting problem.

9. Check The Flywheel Key

The flywheel key, a small metal piece connecting the flywheel to the engine crankshaft, is essential in starting the mantis tiller. If you’re experiencing difficulties getting your tiller started, it’s important to check the condition of the flywheel key.

To do so, remove the spark plug wire and spark plug, followed by the starter housing. Look closely at the flywheel key for any signs of damage or wear. If you notice any issues, such as shearing or damage, replacing the flywheel key with a new one will be necessary.

You can easily obtain replacement flywheel keys from a Mantis dealer or online retailer. Remember, a properly functioning flywheel key is crucial for the smooth operation of your mantis tiller.

10. Check The Tiller Blades

Check The Tiller Blades

If your Mantis tiller refuses to start, one potential cause could be the condition of the tiller blades. Dull or damaged blades can make it challenging for the tiller to penetrate the soil effectively, resulting in difficulty starting the machine.

It is advisable to visually inspect the blades for signs of wear, such as chips or nicks. If you notice any damage, replacing the blades promptly is crucial. Additionally, regular blade sharpening is recommended to maintain optimal performance.

However, if the blades are in good condition, other underlying issues may be causing the starting problem, such as a clogged fuel line or a faulty spark plug. Ensuring the blades are in good shape is just one step in troubleshooting the starting issue of your Mantis tiller.


There can be several reasons why your Mantis Tiller won’t start. It’s important to check each component and perform the necessary troubleshooting steps systematically. From checking the fuel and inspecting the spark plug to verifying the battery and examining the air filter, addressing any issues or malfunctions preventing your tiller from starting is crucial.

Following these troubleshooting steps, you can quickly identify and resolve the problem, getting your Mantis Tiller up and running again in no time. If you’re still experiencing difficulties, it’s recommended to consult a professional for further assistance. Happy gardening!
