39/11/1: Fuller & Johnson
I have a Fuller & Johnson 2 HP hit-and-miss engine Model NB, serial no. 95936. I would like to know the year of the engine and the color code with decal placement. Photos would be helpful. Darrell Tryba, 811 Tryba Road, Hatley, WI 54440.
A: According to Verne Kindschi's The Fuller & Johnson Story II, your engine was made in 1925, the first year of production for the Model NB. Wendel's Notebook lists dark green DuPont 1317, DuPont B8046, PPG/Ditzler 3255 and Sherwin-Williams 6780.

39/11/2: Alaskan generators On a recent trip to Alaska we visited my sister-in-law. They had bought a large farm with no electric power. In a well-built building there are two Witte generator units, one is complete and could be used, the other is a parts engine. The complete engine's serial number is 49268, the parts engine is 49275, and both are 14 HP, 800 rpm, Model CD 14, 5-inch bore and 8-inch stroke with an oil capacity of 11 quarts.

I am in need of the year and a manual for these engines. They are diesel and I know nothing about starting or the like. We want to get this engine up and running for their use. Owen D. Arnett, 6132 Leland Drive, Nampa, ID 83687-9561; (208) 467-4003, (208) 924-0512.

39/11/3: Lauson engines At the Dutton, Ala., Antique Tractor and Engine Show on June 5, I ran into Lewis Skilman, who had a neat-looking Lauson engine for sale. I've been interested in that engine since I had heard of them being used on mini-cars back in the 1930s. We agreed on a price, so I took the engine home to clean it and see if I could make it run. It is a Type RSC 591, no. 7-40919. I removed the flywheel and was surprised to see a magneto like nothing I had seen before. It is an Eiseman magneto built on a 1/8-inch brass plate with seesaw points. I cleaned the magneto thoroughly with spray electric motor cleaner to take away any oxide and dirt that might cause a current leak from the points or condenser (I used a Briggs condenser because I couldn't find one with a screw in the end), and filed the points. Then, I cleaned the carburetor and reset the float level. I had the engine running on the first pull.

At the Piney Chapel Antique Engine and Farm Equipment Show on Aug. 13-14, in Athens, Ala., Lewis Skilman was there again with another Lauson engine mounted with an air pump. I needed air in my shop, so I bought it. The engine is a Type 55S 111, no. 5182516, with a gas tank on the side, a needle valve and a governor-controlled drum carburetor.

There is no name on the carburetor and I have never seen one like it. But it is so simple, I wonder why it wasn't more popular. With the flywheel off, I discovered a similar brass base-plate, but the points and condenser are mounted on a separate plate together. Here again I could not find the same part to replace, so I filed the old points, pried off the old condenser and replaced it with a Briggs & Stratton condenser. The magneto is marked EW 2126 (Eiseman), but the points and condenser are Wico. A new spark plug and wire, cleaning the foot valve in the tank and blowing out the carburetor gave me another running engine. The air pump work well, too.
