If I describe something with the phrase, it's a Honda 160, my brother would know exactly what I am talking about without any further explanation. For you my friend it is; Any mechanical device, found or gifted, that captures ones attention to the extent they will spend endless hours and quite a bit of treasure, trying to restore it. When you find yourself out in the garage in the heat of a LaPlace summer trying to solder together homemade caurberetor floats made from a Band Aid container (Yes the metal ones) you have entered that realm. As far as lawn mowers go, I have always owned Briggs and Stratton machines, so you know I have only owned 3 lawn mowers in the last 68 years.
