This 1917 Holt is 45 Horse Power. It's rated at 600 RPM, but it's only running 325 or so in the video. This engine was used to power a Holt Hillside combine. The opening picture is what I started with. It took me 1 1/2 years to get it running. It took parts of three separate engines to get one running engine. The water pump is a genuine Holt piece from one of the combines i dismantled for the engine parts.
Thanks for watching!!
