Older gasoline lawnmower does not start

I go weekly at my grandma's lawn mowing, with her old gasoline lawnmower. Since I almost always have the problem that the lawnmower does not want to start. Do you know that?

My advice:

Remove the head of the spark plug (usually on the front of the lawnmower), rip some grass or dandelion (or similar) off the ground and rub that green over the spark plug until the green leaves shred or lose minimal liquid. That sends electricity very well!

Put the head of the spark plug back on it and try a few more times to turn on the lawn mower. You will be amazed how well this method works!
