How to use

Turn off the generator and disconnect the spark plug before starting any work. Remove the air filter assembly to access the original carburetor, then detach fuel lines and throttle linkage. Unbolt the old carburetor and fit the replacement unit, ensuring the mounting flange and ports align correctly. Reconnect fuel lines, throttle linkage and any vacuum hoses, install a new gasket where applicable, and reattach the air filter assembly. After installation, check for fuel leaks, reconnect the spark plug, and perform a controlled start-up to verify idle and throttle response. Make small adjustments to the idle and mixture screws according to the generator manufacturer’s service guidance.

Usage recommendations

Use clean, fresh fuel and replace fuel filters if present before installing the carburetor. Inspect and replace old gaskets and hose clamps to ensure a secure seal. If uncertain about adjustments or compatibility, consult a qualified technician or the generator’s service manual to avoid improper setup that could affect engine performance.
