The following story is absolutely true (trust me, I couldn't make this up). Two of my friends borrowed a small garden tiller and subsequently broke it. This is not surprising, given that the terrain in this area is comprised mostly of rocks and clay. Being the courteous people that they are, they sought to have the tiller repaired before returning it to the owner. My one friend took it to her next-door neighbor to look at, as he is one of those Mr. Fix-It types. He told her that the flywheel was broken and that she should take it to a small engine repair place. We live kind of out in the country, so small engine repair places abound out here. You know those places where somebody just sticks a sign out in the front yard declaring his or her particular specialty (small engine repair, upholstery, tax services, hair styling, taxidermy, etc.). The small engine repair places are easier to spot because the front yard is usually littered with broken down lawn mowers. Anyway, my friend called one place that she had patronized in the past and told the gentleman who answered that she had such-and-such a machine with a broken flywheel. He responded that that particular tiller did not have a flywheel. Not having time to deal with it, my friend hung up and let the tiller sit in her car for a few weeks. Finally, she happened to see Mr. Fix-It and she told him about the non-flywheel issue. He kind of rolled his eyes and said "tell them it's a magnetor, they should understand". So she calls back with the new & improved terminology and they tell her to bring it on in. She takes the tiller in and gives the guy (not the same one she talked to on the phone) the broken part, to which he promptly responds...
"That's not a magnetor; that's a flywheel."
