We're having a "common man olympics" where we do dumb things like "unload groceries in one trip" or "hang a picture straight without a level." I want one of the events to be "Start a cranky lawn mower." The problem is, most lawnmowers are easy to start after they have been started the first time, which means the person who goes first has a disadvantage. However, I did have a mower once that was consistently really hard to start. I had to be careful to never let it turn off until I was done mowing. It was actually easier to start the first time. Any ideas how you would go about sabotaging a mower so that it is hard (but not impossible) to start every time? Enough to make you break a sweat, say.
