3. Is it two stroke or 4 stroke?

A two stroke engine mixes a specific amount of oil (it comes in small bottle) into the gasoline. A 4 stroke keeps the gas and oil separate as a car does.

If it’s 4 stroke, change the oil. If it still has gas in it, it may well have gummed up the carburetor. You’ll need to clean or rebuild the carb, and put fresh gas in it.

You may need to change the spark plug and air filter for either type of engine, and sharpen and balance the blade.
