The Starting Rope Of The Lawn Mower Cannot Be Pulled, Possibly Due To A Faulty Spark Plug

If the starting rope of the lawn mower cannot be pulled, it may be due to a faulty spark plug. If the spark plug does not work properly, it cannot generate enough sparks to ignite the mixture, causing the engine to fail to start. The solution is to check if the spark plugs are clean and intact, and replace them with new ones if necessary.
