The model ND introduced in 1930 was little more than a modified NC.  It featured a more sensitive high speed geared flyball governor instead of the old sliding weight style and all sizes were now equipped with disc flywheels.  They were built in 2, 2 1/2 and 3 1/2 hp with all sizes being equipped with a Wico EK magneto as standard equipment.  By the time the ND came along F&J was already in trouble as engine sales continued to slip fast.  Only about 1000 ND engines were made, the last leaving the factory in March of 1933.
