history

In addition to the 1 1/2 horsepower model, Excelsior hopper-cooled engines were built in 3, 5, 6, 8, 10, 12, 14, and 16 horsepower sizes. The 3 and 6-horsepower sizes used an I-beam type connecting rod but all other models featured a turned steel rod. All engines used one-piece valves in a day when most engine valves used a cast iron head with a steel stem. The gasoline tank was in the base, with pump feed to the carburetor. For the biggest jobs, Excelsior offered a series of tank-cooled engines consisting of 8, 10, 12, 14, 16, 18, 20, and 25 horsepower sizes. A special intake valve lock eliminated fluttering on idel strokes with a resultant savings of fuel. In addition to the stationary model, the Excelsior engine was also available as a hopper or screen-cooled portables, hand portables, and saw outfits.
