How to use

Before installation, disconnect the spark plug and drain fuel from the chainsaw tank and carburetor lines. Remove the air filter cover and old carburetor by disconnecting throttle linkage, fuel lines and mounting bolts. Fit the GEKO carburetor into the original position, reconnect fuel lines and throttle linkage, and secure mounting bolts to the manufacturer’s recommended torque. Reinstall the air filter and cover, refill the fuel tank with the correct fuel-oil mixture, reconnect the spark plug, and start the engine. Allow the engine to warm up and then adjust the idle and mixture screws following the chainsaw manufacturer’s tuning procedure to achieve smooth idle and responsive throttle response.

Usage recommendations

Use the GEKO carburetor with fresh, correctly mixed two-stroke fuel and a clean air filter. Perform initial tuning in a safe, well-ventilated area and make only small adjustments to mixture screws, checking engine response after each change. Inspect hoses and gaskets for wear when replacing the carburetor and replace any damaged parts to prevent leaks or performance issues.
