Why won't my Toro HoverPro 550 engine start?
- Tthomas36Aug 6, 2025
If your Toro Lawn Mower engine doesn't start, several factors could be at play. First, ensure the wire is securely connected to the spark plug. If that's not the issue, check the fuel-cap vent for any blockages; clean it or replace the cap if necessary. Inspect the spark plug for pitting, fouling, or incorrect gap, adjusting or replacing it as needed. Finally, verify that the fuel tank isn't empty or filled with stale fuel; drain and refill with fresh gasoline.
