I did it again!! In the April 1992 issue appears an article about a 4 HP United I found in an old pasture, and the owner gave it to me. After solving all the usual problems, it ran great. The thing is, all my friends and acquaintances said I was lucky and it would never happen again, but read on.

Before my retiring from General Motors, I had never even seen one of these old engines, but I talked daily with a co-worker, Curtis Spence, of Ball-ground, Georgia. I then got interested in old iron through another friend.

Over the past few months I managed to add a few more engines to start my collection, but then things began to slow down and it looked as if my luck had run out. Weeks passed, still no engines were located. Then on a Friday night I had a dream and recalled what my old friend Curtis had said a couple of years back about an old 'something' that has two wheels, sitting in the woods back of his house. Needless to say, early Saturday morning I gave Curtis a call. 'Yeah, there's one of them here, my granddaddy used it to saw fire wood years ago.' I made arrangements to see this engine later in the day. Upon arrival at the Spence home, Curtis immediately showed the engine to me. This Nelson Brothers Jumbo was in more than pitiful condition, but after some discussion Curtis said the magic words, 'You can have it!!'

A section was busted off the head, leaving a hole big enough to insert a baseball. All the springs were missing, the valve stems were almost rusted away, the carburetor was in sad shape, butterfly and its valve stem were completely rusted away, the primary fuel tank was rusted beyond repair, the piston was stuck, the water hopper was full of mud, the governor weights were all present but broken, the Webster magneto and ignitor were beyond repair, and the cylinder had frozen and cracked from here to yonder.

First I disassembled all external parts, began the cleaning process and located people to repair all broken parts, then ordered new rings.

The head was repaired and new valve stems made and the governor balls re paired at a local machine shop. Another welding shop repaired the cracked cylinder. The piston came loose with little effort. Next I rebuilt the carburetor as best I could. New slide rod and make shift springs were acquired. Once all the repairs were made and reassembly finished, a spark plug and battery were used for ignition.

Then came the big day. On the first turn of the flywheels, nothing happened. After some carburetor adjustments, the next turn brought a puff of smoke. Then after some adjustments of compression timing, on the next turn of the flywheels she fired and began to run. OH HAPPY DAYS!!

I have always been told that good things happen to those who are patient, and I now believe that dreams do come true. I have enclosed a before and after snapshot. This is a gasoline/kerosene engine and originally used a K-60 Webster magneto and ignitor. The engine brass plate reads: Jumbo, Model DA, 5 HP, No. 3374, Nelson Bros. Co., Saginaw, Michigan.

I understand not much information is available on these engines. If any of you readers can tell me the year built, correct color, etc., etc., I would be grateful. I am now going to bed early, hoping to have another dream come true!!
