Installation Guide
Safety First: Always ensure the engine is cool, the spark plug wire is disconnected, and the fuel line is clamped or drained before beginning any work. Wear appropriate personal protective equipment.
- Preparation: Locate the existing carburetor on your Kohler Courage SV600, SV590, or SV591 engine. Ensure you have all necessary tools, such as wrenches, screwdrivers, and pliers.
- Disconnect Components: Carefully disconnect the fuel line, throttle linkage, choke linkage, and any electrical connections from the old carburetor. Be mindful of fuel spills.
- Remove Old Carburetor: Unbolt the old carburetor from the engine manifold. Note the orientation of any gaskets.
- Install New Gaskets: Place the new gaskets provided with your FTYHFEFH carburetor in the correct positions between the engine, insulator (if present), and the new carburetor.
- Mount New Carburetor: Carefully position the new FTYHFEFH carburetor and secure it with the bolts. Ensure a snug fit without overtightening.
- Reconnect Components: Reconnect the fuel line, throttle linkage, choke linkage, and electrical connections to the new carburetor. Ensure all connections are secure and free of leaks. The provided wiring harness should connect directly to the corresponding terminals.
- Install New Fuel Filter: If replacing the fuel filter, ensure the fuel flow direction is correct.

Operating Principles
The carburetor is a crucial component of your engine's fuel system. Its primary function is to mix air and fuel in the correct ratio for combustion. It atomizes fuel into a fine mist and mixes it with air, then delivers this mixture to the engine's cylinders. The throttle and choke linkages control the amount of air and fuel mixture entering the engine, allowing for varying engine speeds and cold starting. Once installed correctly, the FTYHFEFH carburetor will ensure optimal fuel delivery for efficient engine operation.
Maintenance
Proper maintenance extends the life of your carburetor and ensures optimal engine performance.
- Fuel Quality: Always use fresh, clean fuel. Stale or contaminated fuel can clog carburetor passages.
- Fuel Filter: Regularly inspect and replace the fuel filter (if applicable) to prevent debris from reaching the carburetor.
- Air Filter: Ensure the engine's air filter is clean and properly installed. A dirty air filter can cause a rich fuel mixture.
- Storage: If storing the mower for an extended period, drain the fuel system or use a fuel stabilizer to prevent gumming and varnish buildup in the carburetor.
- Cleaning: For advanced users, periodic cleaning of the carburetor with a specialized carburetor cleaner may be necessary if performance issues arise. Consult a professional if unsure.
Troubleshooting
If you experience issues after installing your new carburetor, consider the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine won't start | No fuel reaching carburetor, clogged fuel filter, incorrect choke setting, loose electrical connection. | Check fuel level, replace fuel filter, ensure choke is set correctly for starting, verify all electrical connections are secure. |
| Engine runs rough/stalls | Improper fuel-air mixture, vacuum leak, dirty air filter, fuel contamination. | Check for air leaks around carburetor gaskets, clean/replace air filter, use fresh fuel. |
| Fuel leaks | Loose fuel line connection, damaged gasket, float bowl issue. | Tighten fuel line clamps, inspect and replace gaskets if damaged, consult a professional for internal carburetor issues. |
