We have a few of them. The first is a 1942 international hopper cooled that came from the farm my dad grew up on. It started in the blacksmith shop, but by the time they moved there, it was in sort of a dog house thing, being used to pump out the septic tank. He just finished restoring it, and just needs to rebuild the magneto to get it running. Then I got an older engine, that looks far newer. It is a 1936 Wisconsin, serial number 8. It has a big gear box on it, weighs about 300#, and puts out 1.8 hp. I hear it came off an old Toro greens mower, rebuild by someone in 1964, then by me a few years ago. The final is likely one of the rarest hopper cooled engines there is. It is an old 2 cylinder novo off an old cement mixer. We could only find one piece of text on it, and no pictures, they were all ran into the ground, and rare to begin with. The only issue is we only have the block, hopper, gas tank, pistons, and valves. The last owner of it died half way through taking it apart. We bought it from his nephew for $40. He said he knows the other parts are in his garage somewhere, and as they clean his stuff out, they will send us any engine parts the find. It will be a very long term projet, but we just couldn't pass up what could be the last of that model in existence.
