Hi Peter, thank you for your question. The carburetors always get gummed up in these small 2-stroke engines from the gas/oil mixture breaking down. Make sure the spark plug is clean and in good working order and that the air cleaner is free of dirt and debris. Locate the 2 adjustment screws on the carburetor. One screw will be for the idle speed or low speed and the other is for the high speed. Turn both screws counterclockwise to back them out. This will set them in the "open" position. Turn each screw clockwise two full turns. This will be the starting point for adjusting the carburetor. Start the engine and let it warm up for a . Adjust the choke lever to help start the engine, if needed.
Turn the screw for the idle speed clockwise until the motor sounds like it is going to stall, then turn it counterclockwise ¼ to ½ turn. Hold the throttle for the engine wide open to run the engine at high rpm. Turn the screw for the high speed counterclockwise until the engine begins to run smooth, then turn it ¼ turn clockwise.
Best Regards
