4.3 Removal of Old Carburetor

- Remove and discard old gaskets. Clean the mounting surfaces thoroughly.
4.4 Installation of New Carburetor
- Install new gaskets on the engine and air filter housing side, ensuring they are correctly oriented.
- Position the new ACTIVLIFE carburetor assembly onto the mounting studs.

- Air Filter: Ensure the air filter is clean and properly installed to prevent dirt from entering the carburetor and engine.
- Storage: If storing the engine for an extended period, drain the fuel system or use a fuel stabilizer to prevent gum and varnish buildup in the carburetor.
7. Troubleshooting
If you experience issues after installing the new carburetor, consider the following common problems:
- Engine Not Starting:
- Check fuel supply and ensure the fuel valve is open.
- Verify spark plug connection and condition.
- Ensure all linkages are correctly connected and moving freely.
- Rough Idling or Stalling:
- Inspect for air leaks around the carburetor gaskets.
- Check for proper adjustment of idle speed (if adjustable on your model).
- Fuel Leaks:
- Ensure fuel lines are securely clamped and not cracked.
- Verify carburetor bowl gasket is properly seated and not damaged.
