How to Change Spark Plugs on Toro Snow Blowers

Toro snow blowers work like most combustion engines. The spark plug provides the charge that sets off combustion. Spark plugs usually have a few seasons of life in them before they give up the ghost. At the beginning of the winter season, check the spark plug for signs of fouling or cracking that may indicate it is faulty. Signs your spark plug may be faulty include failure to start or other erratic engine behavior.
