My mower would not start. On inspection of the spark plug there was wet oil present on both the spark plug and on the thread on the mower.
What maintenance and parts should i inspect/replace in order to fix this problem?
This will be my first attempt at servicing, or for that matter, taking apart a lawn mower. I have not been able to find videos specifically on this problem.
This mower is two years old, and has a 4-cycle engine. The oil level is correct and looks clean. I suspect the problem has come from running too rich; most probably by slowing the mower while i empty it. So in future I will just keep the mower running at full speed.
