How to start a Toro Lawn Mower when the engine won't start?
- H
  hurleyjenniferAug 19, 2025
  If your Toro Lawn Mower engine isn't starting, several factors could be at play. First, ensure your fuel tank isn't empty and that you're using fresh gasoline; stale fuel can prevent ignition. If that's not the issue, and the engine is cold, make sure to use the choke. Also, check that the wire is securely connected to the spark plug. Finally, inspect the spark plug itself for any signs of damage like pitting or fouling, and verify the gap is correct. Replace the spark plug if necessary or adjust the gap.

  Several factors can prevent your Toro Lawn Mower engine from starting. The fuel tank might be empty or contain stale fuel, requiring you to drain and refill it with fresh gasoline. If the engine is cold, ensure the choke lever is in the Choke position. Also, check that the wire is securely connected to the spark plug. Finally, inspect the spark plug itself for pitting, fouling, or incorrect gap; adjust or replace it as needed. If the problem persists after these steps, seek assistance from an Authorized Service Dealer.

  A rough-running engine in your Toro Lawn Mower could be due to a few common problems. First, make sure the wire is securely connected to the spark plug. Also, inspect the spark plug itself—if it's pitted, fouled, or the gap is incorrect, address these issues by adjusting the gap or replacing the plug. Lastly, a dirty air filter element restricting airflow can cause this problem; clean the air filter pre-cleaner and/or replace the paper air filter.

  If your Toro Lawn Mower engine starts hard or loses power, the fuel tank might contain stale fuel, so drain and refill it with fresh gasoline. Check if the fuel cap vent hole is plugged and clean it or replace the fuel cap. A dirty air filter element can restrict airflow, so clean the air filter pre-cleaner and/or replace the paper air filter. Also, clean any clippings and debris from under the mower housing. Inspect the spark plug for pitting, fouling, or an incorrect gap, and adjust or replace it if necessary. Finally, check the engine oil level and change it if it's dirty or add oil if it's low.
