- Drain the fuel tank completely.
- Carefully remove the fuel tank cap and locate the existing fuel lines and grommet.
- Gently pull out the old fuel lines and grommet assembly from the fuel tank.
- Install the new fuel line kit, ensuring the grommet seats properly in the fuel tank opening to prevent leaks.
- Connect the fuel lines to the carburetor and primer bulb as per the original configuration.
2. Air Filter Installation
A clean air filter is essential for proper engine combustion and to prevent dirt from entering the engine.

- Remove the cover of the air filter housing.
- Take out the old, dirty air filter element.
- Insert the new air filter element into the housing, ensuring it fits snugly.
- Replace the air filter housing cover securely.
3. Spark Plug Installation
A new spark plug ensures reliable ignition and efficient engine operation.

- Locate the spark plug on the engine cylinder head.
- Carefully remove the spark plug wire.
- Using a spark plug wrench, unscrew and remove the old spark plug.
- Inspect the new spark plug to ensure the gap is set correctly according to your engine's specifications (refer to your tiller's manual).
- Thread the new spark plug into the cylinder head by hand to avoid cross-threading.
- Tighten the spark plug with a wrench, typically about 1/2 to 3/4 turn after it seats, or to the torque specified in your tiller's manual. Do not overtighten.
- Reconnect the spark plug wire firmly.
Post-Installation Check
After installing all components, perform the following checks:
- Ensure all connections are secure and there are no fuel leaks.
- Check that the air filter housing cover is properly latched.
- Verify the spark plug wire is fully seated on the spark plug.
- Refill the fuel tank with the correct fuel mixture (if applicable for 2-stroke engines).
- Prime the engine using the primer bulb until fuel is visible.
- Attempt to start the engine and listen for smooth operation.
Maintenance Schedule
Regular maintenance is crucial for the longevity and performance of your Mantis tiller. The components in this service kit should be replaced periodically based on usage and operating conditions. Consult your Mantis tiller's owner's manual for specific recommended service intervals. General guidelines include:
- Air Filter: Inspect every 25 hours of operation or annually, replace if dirty or damaged.
- Spark Plug: Replace every 100 hours of operation or annually.
- Fuel Filter & Lines: Inspect annually for cracks, hardening, or clogging. Replace if any issues are found or every 2-3 years as preventative maintenance.
Troubleshooting
If your Mantis tiller is experiencing issues, the components in this service kit often address common problems:
- Engine Not Starting or Hard to Start: A dirty spark plug, clogged fuel filter, or cracked fuel lines can prevent proper fuel delivery or ignition. Replacing these components can resolve such issues.
- Engine Runs Rough or Lacks Power: A restricted air filter can starve the engine of air, leading to poor performance. A fouled spark plug or inconsistent fuel supply from old lines can also cause rough running.
- Fuel Leaks: Old, brittle, or cracked fuel lines are a common cause of fuel leaks. Replacing the entire fuel line kit will address this.
If issues persist after replacing these components, consult a qualified service technician or your Mantis tiller's owner's manual for further diagnostics.
