Without a spark, the fuel is unable to ignite, and the chainsaw won’t be able to start up. Luckily, this is one of the easiest things to check on your chainsaw.
To check for a spark. Locate the spark plug on your chainsaw and remove the cover. Remove the spark plug from the cylinder and attach the spark plug wire to it. Do not put the spark plug back into the cylinder. Touch the spark plugs electrode tip to a metal surface on the engine and pull the starter cord. If you can see sparks, then your spark plug is working.
