4.2. Installation Steps

1. Prepare the Engine: Ensure the engine is cool. Disconnect the spark plug wire. Place a drain pan under the fuel line connection to catch any spilled fuel.
2. Drain Fuel: If necessary, drain the fuel tank or clamp the fuel line to prevent fuel leakage.
3. Remove Air Filter Assembly: Carefully remove the air filter housing and any associated components to gain access to the carburetor.
4. Disconnect Linkages and Fuel Line: Note the routing of all linkages (throttle, choke) and the fuel line. Disconnect them from the old carburetor. Take photos if needed for reassembly.
5. Remove Old Carburetor: Unbolt the old carburetor from the engine manifold. Remove any old gaskets.
6. Clean Mounting Surface: Thoroughly clean the engine manifold mounting surface to ensure a proper seal with the new gaskets.
7. Install New Carburetor: Place new gaskets on the manifold, then mount the ACTIVLIFE Carburetor. Secure it with the bolts, tightening them evenly.
8. Reconnect Linkages and Fuel Line: Reattach the throttle and choke linkages, ensuring they operate smoothly. Connect the fuel line, securing it with a clamp. Consider replacing the fuel filter at this time.
9. Reinstall Air Filter Assembly: Reattach the air filter housing and any other components removed earlier.
10. Reconnect Spark Plug: Reconnect the spark plug wire.

5. Operating Instructions

After installation, follow these steps to start your engine.

1. Add Fuel: Fill the fuel tank with fresh, clean gasoline.
2. Prime the Carburetor: If your engine has a primer bulb, press it several times until fuel is visible in the bulb or fuel lines.
3. Set Choke: Move the choke lever to the 'FULL CHOKE' position for cold starts.
4. Start Engine: Pull the starter rope firmly until the engine attempts to start or runs briefly.
5. Adjust Choke: As the engine warms up, gradually move the choke lever to the 'RUN' position.
6. Idle Adjustment: Allow the engine to warm up for a few minutes. If the idle speed is too high or too low, adjust the idle screw on the carburetor as needed.

6. Maintenance

Regular maintenance helps ensure the longevity and optimal performance of your carburetor and engine.

• Fuel Quality: Always use fresh, clean, and appropriate octane gasoline. Stale or contaminated fuel is a primary cause of carburetor issues. Consider using a fuel stabilizer if the engine will be stored for extended periods.
• Fuel Filter: Regularly inspect and replace the fuel filter according to your engine manufacturer's recommendations. A clogged fuel filter can restrict fuel flow to the carburetor.
• Air Filter: Keep the air filter clean. A dirty air filter can restrict airflow, leading to a rich fuel mixture and poor engine performance.
• Carburetor Cleaning: If the engine experiences rough running or starting issues, the carburetor may need cleaning. This typically involves disassembling the carburetor, cleaning jets and passages with carburetor cleaner, and replacing gaskets. This task is best performed by experienced individuals or a professional.
• Storage: Before long-term storage, run the engine until it runs out of fuel, or drain the fuel system to prevent fuel degradation and gumming in the carburetor.

7. Troubleshooting

If you encounter issues after installing the new carburetor, refer to the following common problems and solutions.

If these troubleshooting steps do not resolve the issue, it is recommended to seek assistance from a qualified small engine mechanic.
