  If your Toro Blower engine won't start, it could be due to several reasons. First, ensure the fuel tank has a fresh fuel/oil mixture. If the tank is full, the spark plug might be shorted or fouled, in which case you should replace it. Also, a broken spark plug (cracked porcelain or electrodes broken) can prevent the engine from starting, so replace it if damaged. Check the ignition lead wire; if it's shorted, broken, or disconnected, replace it or reattach it to the spark plug.

  If your Toro Blower engine lacks power, it might be due to a clogged air filter. Try cleaning or replacing the air filter. A fouled spark plug can also cause this issue, so replace it. Lastly, check for deposits on the spark arrestor, muffler, or exhaust port and clean or replace these parts as needed.

  If your Toro Blower engine is hard to start, it could be due to water in the gasoline or a stale fuel mixture. Drain the entire system and refill it with a fresh fuel/oil mixture. Too much oil in the fuel mixture can also cause this, so drain and refill with the correct fresh fuel/oil mixture. Also, the engine might be under- or over-choked, so adjust the choke as necessary.

  If your Toro Blower engine overheats, it may be caused by insufficient oil in the fuel mixture. Ensure you mix the fuel and oil as described in the starting instructions.
