Method 1: Quick Clean (In-Situ Cleaning)
This method is ideal for minor clogs and requires no carburetor removal. Perfect for beginners!
Safety First!: Disconnect the spark plug wire to prevent accidental starting. Work in a well-ventilated area and wear safety glasses and gloves.
Prepare the Area: Cover the area with rags to catch any spills.
External Cleaning: Use a brush and carburetor cleaner to scrub the exterior of the carburetor thoroughly.
Spray and Soak: Carefully spray carburetor cleaner into the air intake and fuel inlets. Let it sit for 5-10 minutes.
Air it Out: Use compressed air to gently blow out loosened debris.
Reassemble and Test: Reconnect the spark plug wire and test your engine.
Method 2: Deep Clean (Carburetor Removal)
For more stubborn clogs, you may need to remove the carburetor. This requires slightly more mechanical skill. Consult your tractor's manual for specific removal instructions.
Careful Removal: Remove the carburetor, taking photos as you go to aid reassembly.
Locate Jets: Identify the small jets (fuel passages) – these often clog.
Clean the Jets: Use small brushes and compressed air to clean jets thoroughly. Never use metal tools.
Reassemble and Test: Carefully reassemble and retest your engine.
