Important Safety Precautions
- Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, during installation.
- Ensure the engine is completely cool and disconnected from the spark plug wire to prevent accidental starting.

- Dispose of old fuel and parts responsibly according to local environmental regulations.
Installation Instructions
Follow these steps carefully to install the new carburetor kit. If you are unsure about any step, consult a qualified technician or refer to your engine's service manual.
- Prepare the Engine:
Ensure the engine is off and completely cool. Disconnect the spark plug wire to prevent accidental starting. If necessary, drain the fuel tank or use a fuel line clamp to prevent fuel spills during removal.
- Remove Air Filter Assembly:
Locate and remove the air filter cover and the air filter element. You may need to unbolt the entire air filter housing from the engine to access the carburetor.
- Disconnect Fuel Line and Linkages:
Carefully disconnect the fuel line from the old carburetor. Be prepared for minor fuel spills. Disconnect any throttle and choke linkages attached to the carburetor. Take note of their positions or take a photo for easier reassembly.
- Remove Old Carburetor:
Unbolt the old carburetor from the engine. There are typically two or more bolts holding it in place. Remove any old gaskets that may be stuck to the engine or carburetor.
- Clean Mounting Surfaces:
Thoroughly clean the engine's mounting surface where the carburetor attaches. Remove any old gasket material, carbon buildup, or debris to ensure a proper, airtight seal with the new gaskets.
- Install New Gaskets:
Place the new gaskets in their correct positions between the engine, carburetor, and air filter housing. Ensure they are properly aligned with all bolt holes and passages.
- Mount New Carburetor:
Carefully position the new ACTIVLIFE carburetor onto the engine, aligning it with the mounting bolts. Reattach the bolts and tighten them securely, but do not overtighten, as this can damage the carburetor or gaskets.
- Reconnect Fuel Line and Linkages:
Reconnect the fuel line to the new carburetor. Ensure it is securely fastened with a clamp if applicable to prevent leaks. Reattach the throttle and choke linkages to their correct positions. Test their movement to ensure they operate freely without binding.
- Reinstall Air Filter Assembly:
Reinstall the air filter housing, air filter element, and air filter cover. Ensure all components are properly seated and secured.
- Reconnect Spark Plug Wire:
Once all components are installed and secured, reconnect the spark plug wire to the spark plug.
Operating Instructions
After installation, refill the fuel tank with fresh, appropriate fuel for your engine. If your carburetor has a primer bulb, press it several times (typically 3-5 times) until fuel is visible in the bulb or fuel line. Start the engine according to your equipment's manufacturer instructions. Allow the engine to warm up for a few minutes and carefully check for any fuel leaks or unusual operation. If any issues are observed, shut down the engine immediately and refer to the troubleshooting section.
Maintenance
Proper maintenance will extend the life of your carburetor and ensure optimal engine performance.
- Fuel Quality: Always use fresh, clean fuel. Stale or contaminated fuel is a primary cause of carburetor issues. Consider using a fuel stabilizer if the equipment will be stored for extended periods (over 30 days).
- Air Filter: Regularly inspect and clean or replace the air filter according to your engine manufacturer's recommendations. A clogged air filter can restrict airflow and negatively affect carburetor function and engine performance.
- Fuel Filter: If your equipment has an inline fuel filter, inspect and replace it periodically to prevent debris and contaminants from reaching the carburetor.
- Storage: Before long-term storage (e.g., off-season), it is recommended to run the engine until it runs out of fuel, or drain the fuel system completely. This prevents gumming and varnish buildup in the carburetor, which can cause starting and running problems.
Troubleshooting
This section addresses common issues you might encounter after installing the carburetor kit.
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine won't start | No fuel reaching carburetor; spark plug issue; incorrect choke setting | Check fuel level, fuel line for kinks, and fuel filter for blockages. Ensure primer bulb (if present) is working. Verify spark plug connection and condition. Adjust choke. |
| Engine runs rough/stalls | Carburetor jets clogged; air filter dirty; fuel quality issue | Clean carburetor jets (if accessible and you are experienced). Clean or replace air filter. Use fresh fuel. |
| Fuel leaks | Loose fuel line connection; damaged or improperly seated gasket | Check all fuel line connections and tighten clamps. Ensure gaskets are properly seated and not damaged. Replace any compromised gaskets. |
| Lack of power/poor acceleration | Air filter clogged; carburetor not delivering enough fuel; engine governor issue | Clean/replace air filter. Inspect carburetor for blockages. If issues persist, consult an engine service manual or professional. |
