Installation Instructions
This carburetor is a direct replacement for the original unit on Earthquake 33970 Tiller 212cc engines. Follow these steps carefully for proper installation.
- Preparation: Disconnect the spark plug wire. Drain any fuel from the fuel tank and carburetor bowl. Remove the air filter housing and air filter.
- Remove Old Carburetor: Disconnect the fuel line, throttle linkage, and choke linkage from the old carburetor. Unscrew the mounting bolts that secure the carburetor to the engine intake manifold. Carefully remove the old carburetor and any old gaskets.
- Clean Mounting Surface: Thoroughly clean the engine intake manifold surface where the new carburetor will mount. Ensure no old gasket material remains.
- Install New Gaskets: Place the new gaskets in the correct order between the engine, insulator (if present), and the new carburetor. Refer to your tiller's service manual for the exact gasket configuration.
- Mount New Carburetor: Position the new FTYHFEFH carburetor onto the mounting studs/bolts. Secure it with the mounting nuts/bolts, tightening them evenly to prevent air leaks. Do not overtighten.
- Connect Linkages: Reconnect the throttle linkage and choke linkage to the new carburetor. Ensure they operate smoothly without binding.
- Connect Fuel Line: Attach the new fuel line (or the existing one if in good condition) to the carburetor's fuel inlet. Secure with a clamp if necessary.
- Reassemble: Reinstall the air filter and air filter housing. Reconnect the spark plug wire.
- Test: Refill the fuel tank. Start the engine and check for proper operation, including smooth idling and acceleration. Inspect for any fuel leaks.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your carburetor.
- Fuel Quality: Always use fresh, clean fuel. Stale or contaminated fuel is a primary cause of carburetor issues.
- Fuel Filter: Regularly inspect and replace the fuel filter to prevent debris from entering the carburetor.
- Air Filter: Keep the air filter clean to ensure proper air-fuel mixture. A dirty air filter can cause the engine to run rich.
- Storage: If storing the tiller for an extended period, drain the fuel system or use a fuel stabilizer to prevent gum and varnish buildup in the carburetor.
- Cleaning: If performance issues arise, the carburetor may require cleaning. This typically involves disassembling, cleaning with carburetor cleaner, and reassembling with new gaskets. This procedure should only be performed by individuals with mechanical experience.
