1. Once the engine is idling, gradually increase the RPM to around 5,000 RPM.
2. Hold the engine at this RPM for 10-15 minutes.
3. Continue to monitor the engine temperature and make sure it does not exceed 220 degrees Fahrenheit (104 degrees Celsius).

4. Increase the RPM

1. After 10-15 minutes, gradually increase the RPM to around 7,000 RPM.
2. Hold the engine at this RPM for 10-15 minutes.
3. Continue to monitor the engine temperature and make sure it does not exceed 220 degrees Fahrenheit (104 degrees Celsius).

5. Final Adjustments

1. After 10-15 minutes, gradually increase the RPM to the desired operating range.
2. Continue to monitor the engine temperature and make any necessary adjustments to the carburetor or fuel mixture.
3. Once the engine is running smoothly, you can stop the breaking-in process.

Troubleshooting

• Engine is overheating: If the engine temperature exceeds 220 degrees Fahrenheit (104 degrees Celsius), stop the engine and allow it to cool down. Check for any blockages in the cooling system or fuel lines.
• Engine is not running smoothly: If the engine is running rough or stalling, check the glow plug, carburetor, and fuel mixture. Make sure all connections are tight and that the fuel is clean.
