How To Check The Carburetor On A Toro Lawn Mower?
The carburetor is responsible for making the engine run by mixing the fuel with air. If you find your lawn mower suddenly not starting, then you need to check on the carburetor because it can be one of the culprits in this situation.
Here are the steps on how you can check on your lawn mower carburetor:
- Start by turning off and cooling down the engine.
- Once the engine is cooled down, you can remove the air filter cover or hood. Carefully remove the springs from the carburetor, ensuring that it will not rip the gasket.
- Remove the carburetor bowl located at the bottom part of the carburetor assembly. Prepare a rag at the bottom since there might be some fuel that may leave the bowl.
- Unscrew both bolts to remove the bowl from the assembly.
- Check the bowl for crusty build-ups, gummy varnish, or corroded particles. Remove if there are any because they can clog the carburetor jets. You can use carburetor cleaner to clean it.
- If it is impossible to remove the build-ups using cleaners, then a replacement is needed.
- Reinstall the carburetor back in a reverse way to how you removed it.

How To Replace The Spark Plug On A Toro Lawn Mower?
Lawnmowers are not exempted from malfunctions. Different reasons can cause this issue. One of these can be your lawn mower's spark plug.
Here's how you can replace a Toro lawn mower's spark plug to keep your mower operating efficiently:
- The first step is to remove the wire from the spark plug by pulling the rubber boot. Check the condition of the wire.
- Next is to remove the spark plug using a spark plug wrench. This will help protect the spark plug's porcelain insulator because the wrench has rubber cushioning inside.
- You will know if your spark plug needs replacement if the end of the spark plug is black or wet. If it is light gray or tan, then it is still working.
- If replacement is needed, you must ensure that the replacement plug is the same size as the old one. You can also check its porcelain cover and the mower's manual for reference on size and type.
- Check the gap for the spark plug's center electrode and firing electrode to ensure that a proper spark will occur. Some spark plugs are pre-gapped, but you need to check on this using a gap tool.
- Insert the new spark plug back where you removed the old one and use your hand to screw it. Tighten the spark plug using the wrench, but be mindful not to overtighten it.
- Finally, reattach the spark plug wire.
