why does oil keep getting on the spark plug which is stopping my lawn mower from starting

I take it that the engine is a 2-stroke. Are you using the correct 2-stroke oil in the correct petrol to oil ratio. Should probably be 32:1 but check your handbook. You may even be able to go to 40:1 mix which would make it run cleaner. Try a new spark plug of the correct make and grade too
