We have a 19-year-old Honda 4-stroke lawnmower. I maintain it (change oil, clean air filter, sharpen blade, brush spark plug clean and check gap) every year.
It works great, but lately it has been hard to start (pull-cord). It takes many tries to get it going. Once it's started, it runs without a hitch.
I was thinking it might be the spark plug, which is as old as the mower, but I sort of imagined that if that was the problem, that there would also be problems when it's running.
Any ideas ?
Come on. Change the spark plug and let us know if it cures the problem.
After 19 years of cleaning the plug, I can't believe there is anything
"metal" left.....for the spark to jump to.
