4.2 Disassembly

1. Prepare the Mower: Ensure the engine is cool. Disconnect the spark plug wire. Place the mower on a level surface.
2. Drain Fuel: If necessary, drain the fuel tank into an approved container. You may also use a fuel clamp on the fuel line to prevent leakage.
3. Remove Air Filter Assembly: Locate and remove the existing air filter housing. This usually involves unscrewing a few bolts or clips.
4. Disconnect Fuel Line: Carefully disconnect the fuel line from the old carburetor. Be prepared for residual fuel to leak.
5. Disconnect Linkages: Disconnect any throttle and choke linkages attached to the carburetor. Note their positions for reassembly.
6. Remove Old Carburetor: Unscrew the mounting bolts holding the carburetor to the engine. Remove the old carburetor and gasket.

4.3 Installation of New Components

1. Install New Gasket: Ensure the mounting surface on the engine is clean. Place the new gasket provided with the kit onto the engine studs.
2. Mount New Carburetor: Carefully position the new carburetor onto the studs, aligning it with the gasket. Secure it with the mounting bolts, tightening them evenly.
3. Connect Linkages: Reattach the throttle and choke linkages to the new carburetor. Ensure they move freely.
4. Install Fuel Line and Shut-Off Valve: Replace the old fuel line with the new one. Install the new shut-off valve and fuel filter in the fuel line, ensuring the flow direction is correct (arrow points towards the carburetor). Secure connections with the provided hose clamps.
5. Connect Fuel Line to Carburetor: Attach the new fuel line to the carburetor inlet.
6. Install New Air Filter: Place the new air filter into the air filter housing. Reattach the air filter housing to the carburetor.

5. Operating Instructions (Post-Installation)

After successful installation, follow these steps to operate your Craftsman T100 mower:

1. Refill Fuel: Open the fuel shut-off valve and refill the fuel tank with fresh, appropriate fuel.
2. Reconnect Spark Plug: Reconnect the spark plug wire securely.
3. Prime Carburetor (if applicable): Some carburetors may require priming. Refer to your mower's original manual for specific priming procedures.
4. Start Engine: Follow your mower's standard starting procedure (e.g., set choke, pull starter cord).
5. Check for Leaks: Once the engine is running, carefully check all fuel line connections for any leaks. Address any leaks immediately.
6. Engine Break-in: Allow the engine to run for a few minutes to stabilize. Monitor engine performance.

6. Maintenance

Regular maintenance of your carburetor and air filter will ensure optimal engine performance and longevity.

• Air Filter: Inspect the air filter regularly (e.g., every 25 hours of operation or seasonally). Clean or replace it if it appears dirty or clogged. A dirty air filter restricts airflow and can cause the engine to run rich.
• Fuel Filter: Replace the fuel filter annually or if you notice fuel delivery issues. A clogged fuel filter can starve the carburetor of fuel.
• Fuel System Cleaning: If the mower is stored for an extended period, consider draining the fuel or using a fuel stabilizer to prevent gumming in the carburetor.
• Carburetor Adjustment: This carburetor is typically pre-set and does not require extensive adjustment. If performance issues persist, consult a qualified service technician.
