Clean the spark plug if it is black and covered with soot. The soot indicates that the fuel air mixture is not correct. This usually means a dirty carburetor. Use gasoline treatment to clean the carb and keep the gas fresh.

Never leave old gas in your snow blowers gas tank for any length of time. It tends to gum up everything and will cause the condition mentioned above. If the cleaner does not work, the carb will need to be taken apart and cleaned. If you are not familiar with this type of work, it is best to hire a small engine mechanic to complete the work for you.
