vintage 1950s-60s Briggs & Stratton Engine, runs pretty well and has a 3/4in output shaft with a key way. The fuel tank is pretty clean and it looks to be all original besides the pull cord/ fan shroud. I believe the fan shroud was changed because the red paint is not quite the same as the rest of the engine. the fan shroud that's on it is not stamped with any numbers so I don't know the model, type or build date. There's also a dent in the gas tank and the choke lever is broken.
