Setup and Installation
- Preparation:
Ensure the engine is off, cool, and the spark plug wire is disconnected. Drain any fuel from the tank and fuel lines.
- Remove Old Carburetor:
Carefully disconnect the fuel line, throttle linkage, and choke linkage from the old carburetor. Remove the mounting bolts and the old carburetor along with its gaskets. Note the orientation of all parts for reassembly.
- Install New Gaskets:
Clean the mounting surfaces on the engine and intake manifold. Place the new gaskets in their correct positions.

Ensure the gaskets are properly aligned with the mounting holes and air passages.
- Mount New Carburetor:
Position the new FOLIAGE carburetor assembly onto the engine, aligning it with the gaskets and mounting holes. Secure it with the mounting bolts. Do not overtighten; refer to your engine's service manual for specific torque values.
- Connect Linkages and Fuel Line:
Reconnect the throttle and choke linkages to the new carburetor. Ensure they move freely and operate correctly. Attach the new fuel line to the carburetor and secure it with the provided clamps.
- Final Checks:
Double-check all connections, ensuring they are secure. Reconnect the spark plug wire.
Operating Instructions
After installation, follow these general steps to operate your engine:
- Refuel: Fill the fuel tank with the appropriate type of fuel as specified by your engine manufacturer.
- Choke: For cold starts, engage the choke.
- Start Engine: Follow your engine's specific starting procedure (e.g., pull cord, electric start).
- Disengage Choke: Once the engine starts and runs smoothly, gradually disengage the choke.
- Adjustments: If the engine does not run smoothly, minor idle speed or mixture adjustments may be necessary. Refer to your engine's service manual for adjustment procedures.
Maintenance
Regular maintenance ensures optimal performance and longevity of your carburetor.
- Fuel System Cleanliness: Always use fresh, clean fuel. Consider using a fuel stabilizer, especially during storage.
- Fuel Filter: Regularly inspect and replace the fuel filter to prevent contaminants from reaching the carburetor.
- Air Filter: Ensure the air filter is clean and properly installed to prevent dirt from entering the carburetor.
- Seasonal Storage: Before long-term storage, drain the fuel system or run the engine until it runs out of fuel to prevent gum and varnish buildup in the carburetor.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Engine will not start | No fuel, clogged fuel line/filter, incorrect choke setting, spark plug issue. | Check fuel level, inspect fuel line/filter, adjust choke, check spark plug. |
| Engine runs rough/stalls | Dirty carburetor, stale fuel, air filter clogged, incorrect idle adjustment. | Clean carburetor, use fresh fuel, clean/replace air filter, adjust idle. |
| Fuel leaks | Loose fuel line connection, damaged gasket, float bowl issue. | Tighten connections, replace gaskets, inspect float and needle valve. |
If troubleshooting steps do not resolve the issue, consult a qualified service technician or refer to your engine's specific service manual.
