6. Set the throttle to the "FAST" or "START" position.
7. Pull the starter cord firmly or engage the electric starter.

7. Maintenance

Proper maintenance ensures the longevity and optimal performance of your carburetor and snow thrower.

• Fuel Quality: Always use fresh, clean fuel. Stale fuel can cause carburetor issues. Consider using a fuel stabilizer if storing the snow thrower for extended periods.
• Fuel Filter: Regularly inspect and replace the fuel filter (a new one is included in this kit) to prevent contaminants from reaching the carburetor.
• Air Filter: Ensure the air filter is clean and free of debris. A clogged air filter can affect engine performance and fuel mixture.
• Spark Plug: Inspect the spark plug periodically. Replace it if it is fouled or worn (a new one is included in this kit).
• Storage: Before long-term storage, drain the fuel system or run the engine until it runs out of fuel to prevent gumming in the carburetor.
