Side Shaft 7-1/2 hp Gasoline Engine Hit and Miss

This vintage Gasoline engine was built by Ruston-Hornsby Company in 1912. When resistance is applied, and rpm drops, it fires more frequently in order to maintain the rpm. This is much different than the modern day engines that fire regularly on every forth stroke or every second stroke, depending on whether it is a 4 or 2 stroke engine. This video was taken at the 2010 Arlington WA Air Show.

The owner wrote that the engine was most likely used to run an overhead shaft which in turn ran a flex shaft that ran clippers for shearing sheep in the outback of Australia as it was shipped to Sydney from England where it was built.

The tower in the right side was actually the cooling radiator. Water was pumped up to where in ran down over the screens to cool the water.
