MODEL N

In mid 1913 Fuller & Johnson introduced what was to become their most popular hopper cooled engine, the model N. The model N was a hopper cooled gasoline engine with "hit & miss" governing. First made in 1 1/2, 2 1/2, 4, 6, 8 and 10 hp, a 12hp size was later added. These were re-rated to 1 1/2, 3, 5, 7, 9 and 12 hp late in 1916 with the 10hp size being dropped. They differed little from each other except for physical size, the 1 1/2 hp being an exception. This little engine did not have a water cooled head or fly ball governor. The cylinder and base were also cast in a single piece. Over the years of production minor changes were made to these engines. The position of the oilier changed, so did that of the gear driven magnetos. The smaller engines of late manufacture had flywheels with a crowned face and were of a smaller diameter. As time went by the reliable low tension ignition system was replaced with a Wico EK magneto and sparkplug. A kit was also available to convert low tension engines over to the Wico magneto. The model N enjoyed immense success, the larger sizes eventually became the model NB while the smaller ones were phased out and replaced by improved designs.
