Danny, By 1950, Distillate models were all but obsolete, however there were a few Kerosene models still being built. Distillate fuel was most popular during WWII as it was a low grade fuel, cheap, and more plentiful than gasolene. If your tractor was originally a distillate, it would have been designated by the serial number which would have had the prefix of FAA****** with no suffix. Kerosene models had a suffix of X after the numbers. Both distillate and keropsene models were equipped with auxillary fuel tanks so they could be started on gasolene then switched manually to the low grade kerosene or distillate when the engine warmed up enough to give those fuels good combustion. They also were equipped with radiator shutters to allow the engine to run hotter for low grade fuel. Also the manifold was designed with a damper which when closed down would enhance the atomization of low grade fuel not required with gasolene. X1 was the suffix for gasolene models. Either kerosene or distillate models will run just fine on gasolene, however, an X1 gasolene model will not run well with Kerosene or distillate as the engine wont develope enough heat to properly burn the low grade fuel. After the war, many owners of kerosene or distillate models simply filled the main fuel tank with gasolene, opened the shutters all the way, opened the manifold damper, and never burned anything but gasolene from that point on. Through the years, many of those tractors were stripped of the auxillary tanks, shutters, and in particular shutter linkage, and as manifolds needed replaced, installed gasolene (conventional) manifolds. I presently own a 1940 Distillate model A, and with the exception of the manifild, has all the other dual fuel components, but I burn strictly gasolene. The extra goodies as I call them are there for looks only. While your Super A may or may not be a low grade or dual fuel tractor, it too will function fine with gasolene.
