4. Setup and Installation

Installation Steps:
- Prepare the Mower: Ensure the engine is cool. Disconnect the spark plug wire. Place the mower on a stable, level surface.
- Drain Fuel: If necessary, drain the fuel tank into an approved container. Use the included fuel shut-off valve to stop fuel flow if not draining the tank completely.
- Remove Air Filter Assembly: Locate and remove the air filter cover and the air filter element. Disconnect any hoses or linkages attached to the air filter housing.
- Disconnect Fuel Line: Carefully disconnect the fuel line from the old carburetor. Be prepared for residual fuel to leak.
- Disconnect Linkages: Note the position and connection of any throttle or choke linkages attached to the old carburetor. Disconnect them. Taking a photo before removal can be helpful.
- Remove Old Carburetor: Unscrew the mounting bolts or nuts holding the carburetor to the engine. Carefully remove the old carburetor and any old gaskets.
- Clean Mounting Surface: Clean the engine's mounting surface thoroughly to ensure a good seal with the new gasket.
- Install New Gasket/O-ring: Place the new gasket or O-ring (included in the kit) onto the engine's mounting studs or surface.
- Install New Carburetor: Mount the new ACTIVLIFE carburetor onto the engine, ensuring it aligns correctly with the gasket. Secure it with the mounting bolts/nuts, tightening them evenly.
- Reconnect Linkages: Reattach the throttle and choke linkages to the new carburetor in their original positions. Ensure they move freely.
- Install New Fuel Line and Filter: Replace the old fuel line with the new one provided. Install the new fuel filter in the fuel line, ensuring the flow direction is correct (if indicated). Use the new hose clamps to secure connections.
- Install New Spark Plug: Remove the old spark plug and install the new spark plug provided. Tighten to the manufacturer's specifications (typically hand-tight plus a quarter turn).
- Reassemble Air Filter: Reinstall the air filter housing and a new air filter element (if applicable). Secure the cover.
- Refill Fuel: Add fresh, appropriate fuel to the fuel tank.
- Reconnect Spark Plug: Reconnect the spark plug wire.
5. Operating Instructions
After installation, follow these steps for initial start-up and general operation.
Initial Start-up:
- Ensure the fuel shut-off valve (if installed) is in the OPEN position.
- Prime the carburetor if your mower has a primer bulb, following your mower's instructions.
- Set the choke to the appropriate starting position (usually FULL CHOKE for a cold engine).
- Start the engine according to your mower's operating manual (e.g., pull starter cord or engage electric start).
- Once the engine starts, gradually move the choke to the RUN position as the engine warms up.
- Allow the engine to run for a few minutes to ensure proper fuel flow and carburetor function.
General Operation:
- Always operate the mower on a level surface.
- Do not operate the mower in enclosed spaces due to carbon monoxide fumes.
- Regularly check fuel levels and ensure the fuel is fresh.
6. Maintenance
Proper maintenance of your carburetor and fuel system components will extend the life of your lawn mower and ensure reliable operation.
Regular Maintenance Tasks:
- Fuel Filter: Inspect the fuel filter periodically (e.g., every 25 operating hours or annually) and replace it if it appears dirty or clogged.
- Air Filter: Clean or replace the air filter regularly as per your mower's manual. A dirty air filter can restrict airflow and affect carburetor performance.
- Spark Plug: Inspect the spark plug annually or every 50 operating hours. Clean or replace it if electrodes are fouled or worn.
- Fuel Quality: Always use fresh, clean fuel. Stale fuel can cause deposits in the carburetor, leading to starting and running issues. Consider using a fuel stabilizer if storing the mower for extended periods.
- Carburetor Cleaning: If the mower experiences persistent fuel-related issues, the carburetor may require cleaning. This is an advanced task and may require disassembly. Consult a qualified technician if unsure.
7. Troubleshooting
Refer to the table below for common issues and potential solutions related to the carburetor and fuel system.
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine will not start | No fuel, clogged fuel filter, fouled spark plug, incorrect choke setting | Check fuel level, replace fuel filter, replace spark plug, adjust choke. |
| Engine runs rough or stalls | Dirty air filter, stale fuel, carburetor adjustments needed, fuel line obstruction | Clean/replace air filter, use fresh fuel, inspect fuel lines, consider carburetor cleaning/adjustment. |
| Engine lacks power | Dirty air filter, partially clogged fuel filter, incorrect spark plug gap | Clean/replace air filter, replace fuel filter, check/adjust spark plug gap. |
| Fuel leaks from carburetor | Loose connections, damaged gasket/O-ring, float needle issue | Check all connections, replace gasket/O-ring, inspect carburetor float assembly. |
