Recognizing the Symptoms of a Dirty Carburetor
Before you dive into the cleaning process, it’s essential to first identify if your Toro Personal Pace lawn mower is suffering from a dirty carburetor. Here are some common signs that could point towards this issue:
Difficulty Starting
If your mower struggles to start, takes multiple pulls, or sputters before finally firing up, it’s a clear indication that something might be wrong with the fuel delivery system. A dirty carburetor can restrict fuel flow, making it harder for the engine to get the necessary fuel for ignition.
Engine Stalling or Hesitation
A dirty carburetor can also cause the engine to stall or hesitate, especially under load. If your mower runs smoothly at low speeds but starts to sputter or stall when you engage the blades or try to mow uphill, it could be a sign of a clogged carburetor.
Poor Fuel Economy
A dirty carburetor can cause your mower to consume more fuel than usual, resulting in poor fuel economy. If you notice that your mower is using a lot of gas, it’s worth checking the carburetor for any potential issues.
Black Smoke or Exhaust Issues
Excessive black smoke coming from the exhaust indicates that the engine is burning too much fuel. This could be caused by a dirty carburetor that’s not allowing the engine to mix fuel and air correctly.
Engine Running Rough
An engine that runs rough or unevenly is a clear indicator of a potential problem with the carburetor. A dirty carburetor can cause the engine to misfire, resulting in a rough and inconsistent running performance.

Step 4: Clean the Carburetor Parts
- Rinse the parts: After soaking, remove the parts from the cleaner and rinse them thoroughly with clean water.
- Use a brush: For stubborn deposits, use a small brush to scrub the parts, particularly the jets and needle.
- Blow out the jets: Use compressed air to blow out the jets and remove any remaining debris.
Step 5: Reassemble the Carburetor
- Reinstall the jets and needle: Carefully reassemble the jets and needle into their respective places, ensuring they are correctly seated.
- Reinstall the float: Attach the float to the float bowl using the hinge pin.
- Reinstall the float bowl: Secure the float bowl back to the carburetor using the screws.
- Reinstall the carburetor: Attach the carburetor back to the engine using the mounting bolts.
Step 6: Reconnect the Fuel Line
- Connect the fuel line: Carefully connect the fuel line back to the carburetor nipple, ensuring a tight connection.
Step 7: Start the Engine
- Start the mower: Try to start the engine. If it starts and runs smoothly, you’ve successfully cleaned the carburetor!
Important Tips and Considerations
