Haha, I had forgotten about that, I had one too! When I was about 10 maybe, my father said mowing the lawn was going to be my chore and got a beat up old reel-type lawnmower. We tore the engine down and rebuilt it - he said that every boy should know how to do that (he was an engineer). So that mower was my baby. Later we mounted a tank with a hose connected to a special muffler. Would fill the tank with mineral oil that had insecticide in it, then open the valve and fog the yard.
